What you call the psychic being is the mind of the vital. The heart is the seat of this mind. And this mind is the essence of the senses. It receives things from outside, acts upon things that are outside - knows, gives consent, takes interest in them. But this mind cannot be the Ishwara, but it is the knower, the giver of the consent.
The experiences of your past life which are stored within come up to the surface to be rejected. By rejecting all these by and by the inside will have to be cleansed.

The aggressive and quite illogical idea of a single religion for all mankind, a religion universal by the very force of its narrowness, one set of dogmas, one cult, one system of ceremonies, one ecclesiastical ordinance, one array of prohibitions and injunctions which all minds must accept on peril of persecution by men and spiritual rejection or eternal punishment by God, that grotesque creation of human unreason which has been the parent of so much intolerance, cruelty and obscurantism and aggressive fanaticism, has never been able to take firm hold of the Indian mentality.
What is required is faith. Man has body, life and mind but that is not all that constitutes man. He has risen to the mind as a result of evolution. Now a higher consciousness will be evolved - this I call Supermind. It is the instrument of the Divine Consciousness, the Truth-Consciousness.
The Atheist is God playing at hide and seek with Himself; but is the Theist any other? Well, perhaps; for he has seen the shadow of God and clutched at it.
