What Is Mind ?

What is Mind

ätmä sahaiti manasä mana indriyeëa svärthena cendriyamiti krama eña çéghraù
yogo'yameva manasaù kimagamyamasti yasmin mano vrajati tatra gato'yamätmä B.S. 75-3

Translation: The ätma (soul) merges with the mana (mind); the mana merges with the indréyas (senses) and the senses with their respective organs in rapid succession. This entire merger is instantaneous. With such a (strong and intimate) bond is there anything unattainable by the mind? Besides, wherever the mind goes, the soul shall follow.

The atma gets arudha on mana to experience the bhogas. We all have a common thing I in ourselves and that is the only Atma. To understand the basic concepts in Jyotisha such as Arudha, Charakaraka etc. one must know the basics of Vedic Philosophy. To ubderstand the role of Moon i.e. Mind the following series will be a eye opener.

Dewavrat Buit

"He who knows the receptacle (Ayatana) verily becomes the receptacle of his people. Mind is verily the receptacle (of all our knowledge)." (Chhandogya Upanishad, V-i-5)
That which separates you from God is mind. The wall that stands between you and God is mind. Pull the wall down through Om-Chintana or devotion and you will come face to face with God.
The Mind-a Mystery
The vast majority of men know not the existence of the mind and its operations. Even the so-called educated persons know very little of the mind subjectively or of its nature and operations. They have only heard of a mind.
Western psychologists know something.
Western doctors know only a fragment of mind. The afferent nerves bring the sensations from the periphery or extremities of the spinal cord. The sensations then pass to the medulla oblongata at the back of the head, where the fibres decussate. From there, they pass on to the superior frontal gyrus or superior frontal convolution of the brain in the forehead, the supposed seat of the intellect or mind. The mind feels the sensations and sends motor impulses through the afferent nerves to the extremities-hands, legs, etc. It is a brain-function only for them. Mind, according to them, is only an excretion of the brain, like bile from liver. The doctors are still groping in utter darkness. Their minds need drastic flushing for the entry of Hindu philosophical ideas.
It is only the Yogins and those who practise meditation and introspection that know the existence of the mind, its nature, ways and subtle workings. They know also the various methods of subduing the mind.
Mind is one of the Ashta-Prakritis. "Earth, water, fire, air, ether, mind, reason and egoism-these constitute the eightfold division of My Nature" (Gita, VII-4).
Mind is nothing but Atma-Sakti. It is brain that wants rest (sleep), but not the mind. A Yogi who has controlled the mind never sleeps. He gets pure rest from meditation itself.

How The Mind Originated

Mind is Atma-Sakti. It is through mind that Brahman manifests Himself as the differentiated universe with heterogeneous objects. Brahma thought, "There, indeed, are the worlds; I shall create the protectors of the worlds." He gathered the Purusha (Hiranyagarbha) from out of the waters only and fashioned him. He heated him by the heat of meditation. When he was thus heated, his heart burst out. From the heart, the mind came; from the mind the moon, the presiding deity of the mind. (Heart is the seat of the mind; so, the mind came out when the heart burst out. In Samadhi, the mind goes to its original seat, i.e., heart. In sleep also, it rests in the heart with a veil of ignorance between it and Brahman) (Aitareya Upanishad, 1-3-4).
Cosmic Mind And Individual Mind
Hiranyagarbha, otherwise known as Karya Brahman and Sambhuti, is cosmic mind. He is the sum total (Samashti) of all the minds. The individual mind is connected with the cosmic mind. Cosmic mind, Hiranyagarbha, superconscious mind, infinite mind, universal mind are synonymous terms. Different authors have used different terms. Do not be puzzled. Do not be confused. It is Sabda-bheda only.
Hiranyagarbha is cosmic Prana also. He is the Sutratman (thread-like Self). He represents the electric, cosmic, power-house. The different Jivas represent the different, small bulbs. Electricity from the power-house flows through the insulated copper wires into the bulbs. Similarly, the power from Hiranyagarbha flows into the Jivas.
The mind, being very subtle, is in close apposition or contact with other minds, though the human skull intervenes between them. As mind evolves, you come into conscious relation with the mental currents, with the minds of others- near and distant, living and dead. The individual mind of A, although separated from the mind-substance used by other individuals, B, C, D, E, X, Y, etc., by a thin wall of very finest kind of matter, is really in touch with the other apparently separated minds and with the universal mind of which it forms a part.
If A is a friend of B, A's mind is connected with B's mind. The minds of friends, relatives, brothers of A are attached to A's mind. Several minds are similarly linked to B's mind also. The minds of those who are attached to A's mind are, therefore, connected, in turn, with the minds of those who are hanging on B's mind. In this manner, one mind is in touch with all minds in the whole world. This is the Vibhu theory of mind of Raja Yoga.

Mind In Sankhya Philosophy

In Sankhya philosophy, Mahat is the term used to denote "cosmic mind" or "universal mind." It is the first principle that is derived from Avyakta. It is the first principle that is manifested out of the unmanifested Avyakta. The wheel of the bullock-cart rests on the spokes. The spokes rest on the nave. Even so, the mind rests on Prakriti and Prakriti rests on Brahman.
From Mahat comes Ahankara. From Sattvic Ahankara comes mind; from Rajasic Ahankara comes Prana; from Tamasic Ahankara, Tanmatras; from Tanmatras, gross elements; from gross elements, the gross universe. Mind is no other than Ahankara, the idea of 'I'. It is, indeed, difficult to eschew this idea of 'I'. Mind always attaches itself to something objective (Sthula). It cannot stand by itself. It is only this mind that asserts itself as 'I' in this body.
The idea of 'I' is the seed of the tree of mind. The sprout which first springs up from this seed of Ahankara is Buddhi. From this sprout, the ramifying branches called Sankalpas have their origin.
Linga Sarira And Antavaha Sarira
Mind is the most important Tattva of Linga Sarira. Linga Sarira is the astral body or Sukshma Sarira that is linked to the physical body through physical Prana. It separates itself at death from the physical body and travels to Svarga or heaven. It is this body that does Avagamana (coming and going). This body melts in Videha Mukti (disembodied salvation).
There is a difference between Linga Sarira and Antarvaha Sarira. Linga Sarira is astral body with seventeen Tattvas, viz., five Karma-Indriyas, five Jnana-Indriyas, five Pranas, Mind and Buddhi. Antarvaha Sarira is very pure. It is full of Sattva. It is free from Rajas and Tamas. It is with this body that a Yogi passes from one body to another (Parakaya-Pravesa). Lila, through the grace of Sarasvati, came out of the physical body and travelled to higher worlds with this Antarvaha Sarira. You will find this in the Yogavasishtha. Sri Sankaracharya, Raja Vikramaditya, Hastamalaka and Tirumular had Antarvaha Sarira. With the help of this special kind of pure body, they passed into the bodies of other persons. A Yogi with Antarvaha Sarira has Sat-Sankalpa or Suddha Sankalpa.

Mind Is Subtle Matter

Mind is not a gross thing, visible and tangible. Its existence is nowhere seen. Its magnitude cannot be measured. It does not require a space in which to exist.
Mind and matter are two aspects as subject and object of one and the same all-full Brahman, who is neither and yet includes both. Mind precedes matter. This is Vedantic theory. Matter precedes mind. This is scientific theory.
Mind can be said to be immaterial only in the sense that it has not the characteristics of ponderable matter. It is not, however, immaterial in the sense that Brahman (Pure Spirit) as such is. Mind is the subtle form of matter and hence the prompter of the body. Mind is made up of subtle, Sattvic, Apanchikrita (non-quintuplicated) Tanmatric matter. Mind is all electricity. According to the Chhandogya Upanishad, mind is formed out of the subtlest portion of food.
Mind is material. Mind is subtle matter. This discrimination is made on the principle that the soul is the only source of intelligence; it is self-evident; it shines by its own light. But the organs (mind and senses) derive their principle of activity and life from the soul. By themselves, they are lifeless. Hence the soul is always a subject and never an object. Manas can be an object of the soul. And it is a cardinal principle of Vedanta that that which is an object for a subject is non-intelligent (Jada). Even the principle of self-consciousness (Aham Pratyak-Vishayatva) or Ahankara is non-intelligent; it does not exist by its own light. It is the object of apperception to the soul.

The Mental Body

Just as the physical body is composed of solid, liquid and gaseous matter, so also the mind is made up of subtle matter of various grades of density with different rates of vibration. A Raja Yogi penetrates through different layers of mind by intense Sadhana.
The mental body varies much in different people. It is composed of coarse or finer matter, according to the needs of the more or less unfolded consciousness connected with it. In the educated, it is active and well-defined; in the undeveloped, it is cloudy and ill-defined.
There are several zones or slices in the mental body just as there are various compartments in the brain for particular types of thought. During intense anger, the whole mind is suffused with the black hue of malice and ill-will, which expresses itself in coils of thunderous blackness, from which fiery arrows of anger dart forth, seeking to injure the one for which the anger is felt.

Types Of Mind

Every man has a mental world of his own. Every man entirely differs from another man in mode of thinking, temperament, taste, mentality, physical characteristics, etc. Physically also a man differs from another man, although there might be slight resemblance. Observe carefully the nose, the ears, the lips, the eyes, the eyebrows, the arrangement of teeth, the shoulders, hands, fingers, toes, look, voice, gait, way of talking, etc., of different men. You will find vast differences between any two persons. Even the lines of the palm will differ. No two leaves are alike. Variety is the beauty of creation.


Size Of The Mental Body

Mind is atomic (Anu) according to the Nyaya School; is all-pervading (Vibhu) according to the Raja Yoga School of Maharshi Patanjali; is of middling size (same size as that of the body) according to the Vedantic School.
Mental Aura
Mind has got aura (mental aura or psychic aura). Aura is Tejas, brilliance or halo that emanates from the mind. The aura of those who have developed their minds is extremely effulgent. It can travel long distances and affect in a beneficial manner a large number of persons who come under its influence. The spiritual aura is more powerful than either the psychic or Pranic aura.
Influence Of Strong Mind Over Weak Minds
A strong mind has influence over weak minds. A hypnotist with a strong mind hypnotises a whole bunch or circle of boys of weak minds.
There are those among us who are much more sensitively organised than others. As an organism, their bodies are more finely and more sensitively constructed. These, generally speaking, are people who are always more or less affected by the mentalities of others with whom they come in contact, in whose company they are.
He who has purified his mind becomes a centre of force. All the lesser, impure, weak minds are unconsciously drawn towards the purified, greater mind, because they derive peace, power and strength from the greater, purified mind.
Mark the influence of a highly developed mind over a less developed mind. It is impossible to describe what it is like to be in the presence of a Master or developed adept. To sit in his presence, though he hardly speaks a word, is to feel a thrilling sensation so much as to feel new inspirations touching one mentally. It will be an extraordinary experience.
If you want to drink water at a tap, you will have to bend your body. Even so, a lower mind will have to bend (to be humble) before a developed mind if it longs to imbibe its virtues. The thought itself must be calm and unruffled. Then only you can draw inspirations. In such conditions only benign influences can be thrown down into the lower mind from the higher. In such calm, mental states, you can hold communion with God. Planning, angry and depressed moods-all disturb the mind and act as stumbling blocks to God-realisation.

Fourfold Mind Or Antahkarana Chatushtaya

Antahkarana is a term used by the Vedantins to include mind, Buddhi, Chitta and Ahankara. When used in a broad sense, it means the internal instrument. 'Antah' means internal; 'Karana' means instrument. It is the inner instrument (as distinguished from the term Bahya Karana, outer instrument or the senses or Indriyas) through which you sense, perceive, think and reason out.
Ahankara is derived from Prithvi-Tanmatra. (Tanmatras are Sukshma Bhutas or subtle elements. The five gross elements are derived from the Tanmatras.) Chitta is derived from Jala-Tanmatra; Buddhi from Agni-Tanmatra; mind from Vayu-Tanmatra; heart from Akasa-Tanmatra.
Mind is Chetana (intelligent) when compared with the senses. It is Jada (non-intelligent) when compared with Buddhi. Sankhya Buddhi or Buddhi in Sankhya Philosophy is will and intellect combined. Some put Chitta under mind, Ahankara under Buddhi.
Manas, Buddhi, Chitta and Ahankara are only Vritti-bhedas or functional aspects of the mind. The Manas has all things for its objects and extends through the past, present and future; it is one only, but has various functions. You are a Judge when you exercise your judicial powers in the court. You are a cook when you work in the kitchen. You are a president of an association when you sit in the chair in that capacity. You are the same man, but you function differently and you are called by different names according to those different functions. Similarly, when the mind does Sankalpa-Vikalpa (will-thought and doubt), it is called Mind; when it discriminates and decides, it is Buddhi; when it self-arrogates, it is Ahankara; when it is the storehouse of Samskaras and seat of memory, it is Chitta; also when it does Dharana and Anusandhana.
Who gave coolness to water, warmth to fire, motion to air? These qualities are their very nature. Even so, mind has got its Svabhava of running towards objects, Buddhi of determining, Ahankara of self-assertion and self-identification, Chitta of thinking (Smriti) of those objects which are identified by Ahankara.
When the mind is at work, Buddhi and Ahankara work simultaneously along with the mind. Mind, Buddhi and Ahankara work in healthy co-operation. Mind makes Sankalpa-Vikalpa. It thinks whether a certain thing is good or bad. Buddhi comes for determination. It is Buddhi which discriminates the Vishaya (Nischyatmika, Vyavasayatmika).
The Svarupa of mind is thought only. Mind is Sankalpa-Vikalpatmaka. It is Vyakaranatmaka when it forwards the decisions of Buddhi, the messages from Buddhi, to the organs of action for execution. Mind selects, attends and rejects.

Functions Of Mind

Sensation, thought and volition are the threefold functions of the mind. Cognition, desire, volition are the three mental processes.
Mind has three states, viz., active, passive and neutral. Mind always wants variety and new sensations. It is disgusted with monotony.
Law of Association, Law of Continuity and Law of Relativity are the three principal laws of the mind.
These are the characteristics of the mind, viz., change (Parinama), activity (Cheshta), suppression (Nirodha), ideation in action (Sakti), physical life (Jivana), characterisation (Dharma).
Thinking, planning, feeling, knowing are the various activities that are going on in the mind. Sometimes you plan. Sometimes you feel. Sometimes you try to know. Sometimes you think seriously. Sometimes you will (volition). Volition brings all the mental faculties into play. You must be able to know by introspection what exactly is going on at different times in the mind.

Aspects Of Mind

Conscious mind or objective mind, subconscious mind or subjective mind (Chitta) and superconscious mind are three aspects of the mind. You see, hear and read with the objective mind.
Sensational mind, rational mind and intuitive mind are three aspects of mind according to another classification of Western philosophers.
Heart is the seat of four Tattvas-Prana, Mind, Ahankara and Atman. According to Vedanta, the seat of mind is the heart. Ajna Chakra, which consists of two lotuses and which is tentatively situated in the space between the two eyebrows, is the seat of mind according to the Hatha Yoga School.

Seat Of Mind

Mind has various faculties and centres and operates through corresponding physical centres in the brain. Mind, Buddhi and understanding are in the Linga Sarira; but they operate through corresponding centres in the physical brain. The brain is not mind as the Westerners think. Mind has its seat in the physical brain. It gains experiences of this physical universe through the vibrations of the brain.
A king, though he has complete sway over his whole territory, though the whole kingdom belongs to him, has got special places for his residence. He has got a splendid palace in the capital and another beautiful, palatial building in Mussoorie or Mount Abu for his stay in summer. Even so, the mind, though it is all-pervading throughout the body, has got three places to reside in during the three states-Jagrat, Svapna and Sushupti. The seat of mind in deep sleep is heart. In dream, the seat of the mind is neck. In waking state, the seat of the mind is the right eye or Ajna Chakra. Just mark what you do in Alochana (deep thinking). You hold your finger in the chin, turn the neck to the right side, turn the gaze towards the space between the two eyebrows and then begin to think seriously on the problem in hand. This goes to show that the seat of the mind is the Ajna Chakra.

Mind Is Not Atman

In the West, the psychologists make a serious mistake in saying that consciousness is a function and attribute of the mind. It is Chit or Atman only that is Pure Consciousness Itself. Mind borrows its light from time to time from its source-Atman, the Light of lights or the Sun of suns and glitters temporarily like consciousness, like the golden gilt in brass. Mind borrows its light and power from Brahman, the source (Yoni), just as the iron-rod borrows its heat and effulgence from fire. Mind is Jada or non-intelligent, but appears to be intelligent by borrowing light from Brahman, just as water exposed to the sun borrows heat from the sun.
Mind can do only one thing at a time. It is finite (Parichhinna). It is Jada. It is the effect (Karya) of Sattva Guna. It is Vinasi (perishable). It is Chanchala (ever-fluctuating). It is a bundle of ideas, Samskaras, habits, impulses and emotions. It borrows light from the Adhishthana (the underlying substratum), Brahman. You can control the mind. The thinker is different from thought. There is no functioning of the mind in deep sleep. You always say, "My mind", as if mind is one of your instruments just like your walking-stick or umbrella. Therefore, mind is not the self-shining Atman.
Even in cases of delirium or in cases where there is paralysis of the mental functions, where a man loses his memory and other faculties partly or wholly, 'He' remains. The 'I' exists (Aham Asmi). The mind seems to be as much your property and outside of you as the limbs, the dress worn or the building you dwell in. Therefore, mind is different from 'I'.
Mind gropes in darkness. It forgets every moment. It is changing every second. If food is withdrawn for a couple of days, it cannot think properly. There is no functioning of the mind during deep sleep. It is full of impurities, Vasanas and Trishnas (cravings). It gets puzzled during anger. In fear, it trembles. In shock, it sinks. How can you take the mind, then, as the pure Self?
Manas is an organ of sensation and thought. This instrument must be under the control of someone who uses it. The Jiva or human soul is not the director of the mind, because we see that ordinary men cannot control their minds. They are simply swayed hither and thither by petty Raga-Dvesha, emotion and fear. Therefore, there must exist some other Being, who is Director of the mind. Who is that Being? He is the Manasah pati (Lord of mind), Antaryamin, Kutastha Brahman.
Just as you see the tree in front of you, there must be somebody to see and know what is going on in the mind of Jivas. That somebody is Kutastha. Kutastha is Brahman Himself. There is a tumbler in front of you. It cannot see itself. An instrument, eye and a seer are needed. If you say that the tumbler can see itself, then there will be Karmakartritva-bhava-virodha. It is a logical absurdity. Therefore, you have to admit that there is a silent Sakshi of the mind, who is eternal, unchanging, eternal knower, always the knowing subject. He is witnessing the motives and modifications that arise in the minds of Jivas.
Isvara or Saguna Brahman (Personal God) has full consciousness of Nirguna Brahman. That is His Svarupa- Lakshana. At the same time, he has full cosmic consciousness. He knows what is going on in every mind.
Consciousness per se or the Absolute Consciousness is common in all. This pure consciousness is one. It is Kutastha Chaitanya. All the workings of the mind, all modifications that arise in the minds of all are presented to the one common consciousness which is the witness of the mental Vrittis. Even though consciousness is one, when Rama is stung by a scorpion, only Rama feels and not his friend Krishna who is standing near him. Antahkarana or mind is different in every individual. It is Antahkarana that limits a man who is, in reality, identical with the Brahman or Supreme Soul! This identity is realised when the Avarana or veil of ignorance is removed.
The mind is an object of perception for Brahman. Atman directly cognises all the phenomena of the mind, viz., desire, imagination, doubt, belief, disbelief, shame, intelligence, fear, etc. He remains Himself quite unattached and unaffected like the omnipresent ether, like the crystal which reflects different coloured objects, like the sun.

Atman-the Source For The Mind

Manas, which expands through Sankalpas and Vikalpas, is generated with Brahman as its cause. The form which the endless Atman (Supreme Spirit) assumes through Sankalpa is Manas (mind). It first turned its back to discrimination and hence entangled itself in the folds of Vasanas of objects. The underlying substratum, Adhishthana of the mind, the source or basis for mind is Atman or Brahman or Absolute Conscious- ness. The Power of powers who gives power to the mind, the Light of lights who sheds light on the mind, the Seer of seers who witnesses the motives of and movements in the mind, the Support of supports on which the mind rests in sleep is BRAHMAN.
"Om Keneshitam Patati Preshitam Manah-Willed and directed by whom does the mind go towards its desired objects?" (Kenopanishad). To that Power of powers I bow with folded hands. That Power of powers I am (Soham, Sivoham).
That Secondless Supreme Being who resides in the chambers of your hearts as Antaryamin or Inner Ruler or Controller or Sutradhara or Sakshi (silent Witness), Antaratman (Inner Self), who has no beginning, middle or end, who is the source of this world, the Vedas, body, mind, Indriyas and Prana, who is all-pervading, who is unchanging, who is One Homogeneous Essence (Ekarasa), who exists in the past, present and future, who is self-existent (Svayambhu), who is independent (Svatantra) and who is self-luminous (Svayam- jyotis) is God or Atman or Brahman or Purusha or Chaitanya or Bhagavan or Purushottama.
During dream, you are splendid, effulgent light. Where does it come from? From Atman. The light that is present in the dream clearly indicates that Atman is self-luminous (Svayamjyotis, Svaprakasha).
God is Truth. God is Love. God is Light of lights. God is Peace. God is Knowledge. God is the embodiment of Bliss. God is Sat-Chit-Ananda-Existence Absolute, Knowledge Absolute and Bliss Absolute. God is Eternity. God is Immortality. God is Infinity. God is Avinasi, Supreme Vastu. God is All-pervading Essence or Substance. God is the only Sara Vastu. God is Infinite Beauty.
Bhagavan is a synonymous term for God. He who has the six attributes, viz., Jnana (wisdom), Vairagya (dispassion), Yasas (fame), Aisvarya (divine powers), Sri (wealth) and Dharma (righteousness) in their fullest measure is Bhagavan.
According to Vayu Purana, "Omniscience, satisfaction, eternal knowledge, independence, constant presence of power, infinity of power-these six are said to be the aspects (Angas) of the Great Lord."
Sarvajnatva (omniscience, knowledge of all the worlds, their Jivas and their Karmas), Sarvesvaratva (supreme rulership of all, the power of dispensing the fruits of all Jivas), Sarvantaryamitva (inner control of all names and forms and all Indriyas and minds), Sarvakaranatva (causality for the creation, preservation and destruction of all), Sarvaniyantritva (doing everything without failure of Niyama), Sarvakartritva (the doing of all actions), Sarvasaktimatva (omnipotence), Svatantratva (absolute independence) are the eight attributes of God.
"Knowledge, desireless, power of control, purificatory action, truth, forgiveness, endurance, creation, the Knowledge of the Self, and being the substratum of all activities-these ten unchangeable (Avyaya) qualities always live in the Great Source of all Good."
Srishti (creation), Sthiti (preservation), Samhara (destruction), Tirodhana (veiling) and Anugraha (blessing) are the five kinds of action (Panchakrityas) of God.
God is the Niyamaka (ruler), Antaryamin (knower of the heart) and Preraka (prompter) also. He helps the Sadhakas in a variety of ways, viz., through dreams, the Inner Voice, by talking through the mouths of others in daily conversations and advice from friends.
Nitya Sukha (eternal bliss), Parama Santi (supreme peace), Nitya Tripti (eternal satisfaction), infinite happiness, Akhanda Sukha (unbroken joy) can be had only in God. Attain this God-consciousness or Self-realisation or Darshana of God through Ananya Bhakti or Vichara. This is the goal of life. This is your highest duty. All other duties are secondary.
The essence of Indriyas is the mind; the essence of mind is Buddhi; the essence of Buddhi is Ahankara; the essence of Ahankara is Jiva (the individual soul). Brahman or Suddha Chaitanya is the womb or Yoni or Adhishthana or substratum for everything. He is the Sakshi or witness of everything.
Atman is the proprietor of a big firm, this mental factory. Buddhi is the manager. Mind is the head clerk. The head clerk has got two functions to perform. He gets direct orders from the manager and he has to supervise the workmen also. Even so, the mind has got two functions. It has connections with the Buddhi, the manager and Karma-Indriyas, the workers.
Mind is more internal than speech. Buddhi (intellect) is more internal than the mind. Ahankara is more internal than Buddhi. Jiva Chaitanya (Abhasa, reflected intelligence) is more internal than Ahankara. Atman or Kutastha is more internal than the Jiva Chaitanya. There is nothing internal to Atman. It is Paripurna (All-Full).
When, by analysing your own mind, you come face to face with something which is never destroyed, something which is by its own nature eternally pure, perfect, self-luminous and unchanging, you will no longer be miserable, no more unhappy.
One Essence only exists. It is One without a second (Ekameva Advitiyam Brahma). It is Ananta, spotless, ever pure and Paripurna. Meditate upon It without fluctuation of mind and free yourself from all pains with true calmness of mind. Being quite unreal, Ahankara will perish through efforts.
