The man who is impatient to arrive at spiritual realization is to be envied. As Omar Khayyam says, "Tomorrow? Why, tomorrow I may be myself with yesterday's seven thousand years." He means by this, "Don't bother about the past, don't trouble about the future, but accomplish all you can just now." Life has taken time enough to develop gradually from mineral to vegetable, from vegetable to animal, and from animal to man, and after becoming man delay is not necessary. It is true that the whole lifetime is not sufficient for one to become what one wishes to be. Still nothing is impossible, since the soul of man is from the spirit of God; and if God can do all things why cannot man do something?
