Vital... is a thing of desires, impulses, force-pushes, emotions, sensations, seekings after life-fulfilment, possession and enjoyment; these are its functions and its nature; — it is that part of us which seeks after life and its movements for their own sake and it does not want to leave hold of them if they bring it suffering as well as or more than pleasure; it is even capable of luxuriating in tears and suffering as part of the drama of life. What then is there in common between the thinking intelligence and the vital and why should the latter obey the mind and not follow its own nature? The disobedience is perfectly normal instead of being, as Augustine suggests, unintelligible. Of course, man can establish a mental control over his vital and in so far as he does it he is a man, — because the thinking mind is a nobler and more enlightened entity and consciousness than the vital and ought, therefore, to rule and, if the mental will is strong, can rule. But this rule is precarious, incomplete and held only by much self-discipline. For if the mind is more enlightened, the vital is nearer to earth, more intense, vehement, more directly able to touch the body. There is too a vital mind which lives by imagination, thoughts of desire, will to act and enjoy from its own impulse and this is able to seize on the reason itself and make it its auxiliary and its justifying counsel and supplier of pleas and excuses. There is also the sheer force of Desire in man which is the vital’s principal support and strong enough to sweep off the reason, as the Gita says, “like a boat on stormy waters”, na ̄vamiva ̄mbhasi.
—Sri Aurobindo, Letters on Yoga, p. 329
… the vital is the Life-nature made up of desires, sensations, feelings, passions, energies of action, will of desire, reactions of the desire-soul in man and of all that play of possessive and other related instincts, anger, fear, greed, lust, etc., that belong to this field of the nature.
—Sri Aurobindo, Letters on Yoga, p. 327
The vital has to be carefully distinguished from mind, even though it has a mind element transfused into it; the vital is the Life-nature made up of desires, sensations, feelings, passions, energies of action, will of desire, reactions of the desire-soul in man and of all that play of possessive and other related instincts, anger, fear, greed, lust, etc., that belong to this field of the nature. Mind and vital are mixed up on the surface of the consciousness, but they are quite separate forces in themselves and as soon as one gets behind the ordinary surface consciousness one sees them as separate, discovers their distinction and can with the aid of this knowledge analyse their surface mixtures.
