Therefore Krishna teaches us not to shirk our duties, but to take them up manfully, and not think of the result. The servant has no right to question. The soldier has no right to reason. Go forward, and do not pay too much attention to the nature of the work you have to do. Ask your mind if you are unselfish. If you are, never mind anything, nothing can resist you! Plunge in! Do the duty at hand. And when you have done this, by degrees you will realise the Truth: "Whosoever in the midst of intense activity finds intense peace, whosoever in the midst of the greatest peace finds the greatest activity, he is a Yogi, he is a great soul, he has arrived at perfection."
