Question: It has been scientifically proven that we only use a small section of our brain. Do we use more of the brain when we are enlightened?

Babaji:

It is possible, but for a Yogi it is not very interesting. You only need a little of the mind's functioning to work in this world. So using more of the brain might be interesting for people of this world, but not for a Yogi.

This relationship between the brain and the mind is very peculiar. When the mind gets sucked into the brain, it becomes the brain's food. As long as the brain is functioning, it reflects the mind. Then the problems start as the mind gets agitated. As a Yogi, one needs only a minimum amount of the mind to function in this world.
