If you desire to be pure, have firm faith, and slowly go on with your devotional practices without wasting your energy in useless scriptural discussions and arguments.
Hanuman, the devotee of Rama, said: When I identify myself with the body, O Lord, I am Thy creature, eternally separate from Thee. When I identify myself with the soul, I am a spark of that Divine Fire which Thou art. But when I identify myself with the Atman, I and Thou art one.
