Oh friend! Brahma Jnana means realisation of Self (Atma). There is no difference between Atma and God. If you want to realise Atma in your body, then you have to surrender to God the following five things: five pranas, five senses, mind, intellect and ego. All these are inside a person. It is easy to surrender the external things. But to surrender those which are inside a person is very difficult. It is like walking on the edge of a sharp knife. Those who cannot surrender even the external things are deemed to be fully under delusion. Such persons cannot understand the five inside matters.
