My doctrine means that I must identify myself with life, with everything that lives, that I must share the majesty of life in the presence of God. The sum-total of this life is God. .. Man is not at peace with himself until he has become like unto God. The endeavor to reach this state is the supreme, the only ambition worth having. And this is self-realisation. This self-realisation is the subject of the Gita, as it is of all scriptures... to be a real devotee is to realise oneself. Self-realisation is not something apart.
