There is a difference between the brain and the mind. The brain is separative, functional; it cannot see the whole and functions within a pattern. The mind is the totality which can see the whole. The brain is contained within the mind, but the brain does not contain the mind. However much thought may purify itself, refine itself, control itself, it cannot possibly conceive or formulate or understand what is the total. It is the capacity of the mind that sees the whole, not the brain.
