For those who are treading the spiritual path it is as necessary to think of the world, especially at the present time, as it is to think of someone else and of themselves. No one should think that by position or rank, by profession or occupation, by condition or situation, he is too limited to think of the world; but each of us should realize that we are a self-sufficient particle of the whole. Each particle is responsible for the evolution of the world in proportion to the place it occupies in the cosmos; and everything a man naturally knows first about himself, and then about another, is of the greatest importance when he also begins to know something about the world at large. What he should know is what the world was, what the world is now, and what it will be in the future.
