Hinduism is a living organism. One and indivisible at the root, it has grown into a vast tree with innumerable branches. Knowledge is limitless and so also the application of truth. Everyday we add to our knowledge of the power of Atman (soul) and we shall keep on doing so.
The man who eats to live, who is friends with the five powers - earth, water, ether, sun and air - who is a servant of God, the Creator of all these, ought not to fall ill.
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.
If we are to reach real peace in this world and if we are to carry on a real war against war, we shall have to begin with children; and if they will grow up in their natural innocence, we won't have to struggle; we won't have to pass fruitless idle resolutions, but we shall go from love to love and peace to peace, until at last all the corners of the world are covered with that peace and love for which consciously or unconsciously the whole world is hungering.
He who runs to the doctor, vaidya, or hakim for every little ailment, and swallows all kinds of vegetable and mineral drugs, not only curtails his life, but by becoming the slave of his body instead of remaining its master, loses self-control, and ceases to be a man.
