(4) 'The senses they call the horses, the objects of the senses their roads. When he (the Highest Self) is in union with the body, the senses, and the mind, then wise people call him the Enjoyer.'

(1) Pleasure and distress, fear and courage, desire and aversion, where have these affections and experiences their seat?

Clearly, either in the Soul alone, or in the Soul as employing the body, or in some third entity deriving from both. And for this third entity, again, there are two possible modes: it might be either a blend or a distinct form due to the blending.

And what applies to the affections applies also to whatsoever acts, physical or mental, spring from them.

We have, therefore, to examine discursive-reason and the ordinary mental action upon objects of sense, and enquire whether these have the one seat with the affections and experiences, or perhaps sometimes the one seat, sometimes another.

And we must consider also our acts of Intellection, their mode and their seat.

And this very examining principle, which investigates and decides in these matters, must be brought to light.

Firstly, what is the seat of Sense-Perception? This is the obvious beginning since the affections and experiences either are sensations of some kind or at least never occur apart from sensation.

(10) 'Beyond the senses there are the objects, beyond the objects there is the mind, beyond the mind there is the intellect, the Great Self is beyond the intellect.'

(3) The mind, verily, is an apprehender. It is seized by desire as an over-apprehender, for by the mind one desires desires.

(9) That subtle Self is to be known by thought (ketas) there where breath has entered fivefold, for every thought of men is interwoven with the senses, and when thought is purified, then the Self arises.

(1) Let a man meditate on the fivefold Sâman, which is greater than great, as the prânas (senses). The hiṅkâra is smell (nose), the prastâva speech (tongue), the udgîtha sight (eye), the pratihâra hearing (ear), the nidhana mind. These are one greater than the other.

(5) 'He who knows, let me think this, he is the Self, the mind is his divine eye . He, the Self, seeing these pleasures (which to others are hidden like a buried treasure of gold) through his divine eye, i. e. the mind, rejoices. 'The Devas who are in the world of Brahman meditate on that Self (as taught by Pragâpati to Indra, and by Indra to the Devas). Therefore all worlds belong to them, and all desires. He who knows that Self and understands it, obtains all worlds and all desires.' Thus said Pragâpati, yea, thus said Pragâpati.

(23) I explain: A living body is illuminated by soul: each organ and member participates in soul after some manner peculiar to itself; the organ is adapted to a certain function, and this fitness is the vehicle of the soul-faculty under which the function is performed; thus the seeing faculty acts through the eyes, the hearing faculty through the ears, the tasting faculty through the tongue, the faculty of smelling through the nostrils, and the faculty of sentient touch is present throughout, since in this particular form of perception the entire body is an instrument in the soul's service.

The vehicles of touch are mainly centred in the nerves- which moreover are vehicles of the faculty by which the movements of the living being are affected- in them the soul-faculty concerned makes itself present; the nerves start from the brain. The brain therefore has been considered as the centre and seat of the principle which determines feeling and impulse and the entire act of the organism as a living thing; where the instruments are found to be linked, there the operating faculty is assumed to be situated. But it would be wiser to say only that there is situated the first activity of the operating faculty: the power to be exercised by the operator- in keeping with the particular instrument- must be considered as concentrated at the point at which the instrument is to be first applied; or, since the soul's faculty is of universal scope the sounder statement is that the point of origin of the instrument is the point of origin of the act.

Now, the faculty presiding over sensation and impulse is vested in the sensitive and representative soul; it draws upon the Reason-Principle immediately above itself; downward, it is in contact with an inferior of its own: on this analogy the uppermost member of the living being was taken by the ancients to be obviously its seat; they lodged it in the brain, or not exactly in the brain but in that sensitive part which is the medium through which the Reason-Principle impinges upon the brain. They saw that something must be definitely allocated to body- at the point most receptive of the act of reason- while something, utterly isolated from body must be in contact with that superior thing which is a form of soul of that soul apt to the appropriation of the perceptions originating in the Reason-Principle.

Such a linking there must be, since in perception there is some element of judging, in representation something intuitional, and since impulse and appetite derive from representation and reason. The reasoning faculty, therefore, is present where these experiences occur, present not as in a place but in the fact that what is there draws upon it. As regards perception we have already explained in what sense it is local.

But every living being includes the vegetal principle, that principle of growth and nourishment which maintains the organism by means of the blood; this nourishing medium is contained in the veins; the veins and blood have their origin in the liver: from observation of these facts the power concerned was assigned a place; the phase of the soul which has to do with desire was allocated to the liver. Certainly what brings to birth and nourishes and gives growth must have the desire of these functions. Blood- subtle, light, swift, pure- is the vehicle most apt to animal spirit: the heart, then, its well-spring, the place where such blood is sifted into being, is taken as the fixed centre of the ebullition of the passionate nature.

(3) 'Know the Self to be sitting in the chariot, the body to be the chariot, the intellect (buddhi) the charioteer, and the mind the reins.'

(25) But the organ is not the only requisite to vision or to perception of any kind: there must be a state of the soul inclining it towards the sphere of sense.

Now it is the soul's character to be ever in the Intellectual sphere, and even though it were apt to sense-perception, this could not accompany that intention towards the highest; to ourselves when absorbed in the Intellectual, vision and the other acts of sense are in abeyance for the time; and, in general, any special attention blurs every other. The desire of apprehension from part to part- a subject examining itself- is merely curiosity even in beings of our own standing, and, unless for some definite purpose, is waste of energy: and the desire to apprehend something external- for the sake of a pleasant sight- is the sign of suffering or deficiency.

Smelling, tasting flavours may perhaps be described as mere accessories, distractions of the soul, while seeing and hearing would belong to the sun and the other heavenly bodies as incidentals to their being. This would not be unreasonable if seeing and hearing are means by which they apply themselves to their function.

But if they so apply themselves, they must have memory; it is impossible that they should have no remembrance if they are to be benefactors, their service could not exist without memory.

(70) From whence the senses and thoughts exist, so that one quality seeth the others, which are also in it, and tempered with itself, and proveth them with its sharpness, so that there cometh to be but one will; which in the body riseth up in the first fountainsource or wellspring in the astringent or harsh quality.

(7) He who understands all and who knows all, he to whom all this glory in the world belongs, the Self, is placed in the ether, in the heavenly city of Brahman (the heart). He assumes the nature of mind, and becomes the guide of the body of the senses. He subsists in food, in close proximity to the heart. The wise who understand this, behold the Immortal which shines forth full of bliss.

(3) These are the hindrances: the darkness of unwisdom, self-assertion, lust hate, attachment.

(4) 'Now where the sight has entered into the void (the open space, the black pupil of the eye), there is the person of the eye, the eye itself is the instrument of seeing. He who knows, let me smell this, he is the Self, the nose is the instrument of smelling. He who knows, let me say this, he is the Self, the tongue is the instrument of saying. He who knows, let me hear this, he is the Self, the ear is the instrument of hearing.

(47) Mastery over the powers of perception and action comes through perfectly concentrated Meditation on their fivefold forms; namely, their power to grasp their distinctive nature, the element of self-consciousness in them, their inherence, and their purposiveness.

(11) Through the corporeal spirit, then, man perceives, desires, rejoices, is angry, is nourished, grows. It is by it, too, that thoughts and conceptions advance to actions. And when it masters the desires, the ruling faculty reigns.

(12) But the reasoning faculty, being peculiar to the human soul, ought not to be impelled similarly with the irrational animals, but ought to discriminate appearances, and not to be carried away by them. The powers, then, of which we have spoken hold out beautiful sights, and honours, and adulteries, and pleasures, and such like alluring phantasies before facile spirits; as those who drive away cattle hold, out branches to them. Then, having beguiled those incapable of distinguishing the true from the false pleasure, and the fading and meretricious from the holy beauty, they lead them into slavery. And each deceit, by pressing constantly on the spirit, impresses its image on it; and the soul unwittingly carries about the image of the passion, which takes its rise from the bait and our consent.
