Since mind has no origin, it has never come into existence in the first place. Now it is not located anywhere, inside or outside the body. Finally, the mind is not some object that goes somewhere or ceases to exist. By examining and investigating the mind, you should come to a precise and certain understanding of the nature of awareness, which has no origin, location, or cessation.
