Bhagavad Gita -Sri Madhvacharya
(Bhashya and Tatparya Nirnaya)
Bhashya :- Even then, in the absence of realization, there is sorrow. Therefore, it is clarified, by contact of senses. is that which is sense experienced. is having contact with them. Those (contacts), verily, are cold and heat, pleasure and pain. The body having contact with cold and heat, pleasure and pain, the Consciousness appears to experience cold and heat, pleasure and pain. Therefore are the pleasures and the pains.The experience of sorrow etc. does not affect the Consciousness, by itself. Why ? Because they come and go. If their contact was with the Consciousness, then-they should have existed even in deep sleep. Therefore, since the contact with senses is experienced only in the waking state and not in other states it is concluded that only when there is contact (with the body) which includes mind only then there is the effect. Therefore, it is not the Consciousness (that is affected). For the Consciousness, there is no contact except when it seeks relationship through the experience of the senses. Because of the nature of their coming and going in the form of a flowing river, they cannot be said to be eternal in the absence of such flow in deep sleep. Hence it is said to be not eternal. Consequently, when the Consciousness is deluded relating itself with the body, pleasure and pain are caused. When these two (the Consciousness and the body) are considered as separate, then the sorrow arising from death of the kith and kin would not arise. Therefore, giving up such affiliation with the Consciousness, perceive cold, heat and the rest.
