There are subjects where reason cannot take us far and we have to accept things on faith. Faith then does not contradict reason but transcends it. Faith is a kind of sixth sense which works in cases which are without the purview of reason.
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.
I was a coward. I used to be haunted by the fear of thieves, ghosts and serpents. I did not dare to stir out of doors at night. Darkness was a terror to me. It was almost impossible for me to sleep in the dark, as I would imagine ghosts coming from one direction, thieves from another and serpents from a third. I could not therefore bear to sleep without a light in the room.
