What you feel, see, hear, smell, taste are what the mind perceives. Nerve impulses, in fact.

Who controls them? 

External forces? Cannot be.. Who are you if you cannot condition your own body?

OK suppose you cannot condition your body. Then it is not yours. Why do you give so much importance to it? Look inward :)

If you can condition your body, then you do not depend on external forces. Look inward! :)

Aham Brahmam Asmi :)
