Strength, strength is what the Upanishads speak to me from every page. This is the one great thing to remember, it has been the one great lesson I have been taught in my life; strength, it says, strength, O man, be not weak. Are there no human weaknesses? - says man.

Strength, O man, strength, say the Upanishads, stand up and be strong.
