“Suffering is not enough. Life is both dreadful and wonderful… How can I smile when I am filled with so much sorrow? It is natural--you need to smile to your sorrow because you are more than your sorrow.”

The Time of Your Life (1939)
Context: Remember that every man is a variation of yourself. No man's guilt is not yours, nor is any man's innocence a thing apart. Despise evil and ungodliness, but not men of ungodliness or evil. These, understand. Have no shame in being kindly and gentle, but if the time comes in the time of your life to kill, kill and have no regret. In the time of your life, live — so that in the wondrous time you shall not add to the misery and sorrow of the world, but shall smile to the infinite delight and mystery of it.
Context: In the time of your life, live — so that in that good time there shall be no ugliness or death for yourself or for any life your life touches. Seek goodness everywhere, and when it is found, bring it out of its hiding-place and let it be free and unashamed. Place in matter and in flesh the least of the values, for these are things that hold death and must pass away. Discover in all things that which shines and is beyond corruption. Encourage virtue in whatever heart it may have been driven into secrecy and sorrow by the shame and terror of the world. Ignore the obvious, for it is unworthy of the clear eye and the kindly heart. Be the inferior of no man, nor of any man be the superior. Remember that every man is a variation of yourself. No man's guilt is not yours, nor is any man's innocence a thing apart. Despise evil and ungodliness, but not men of ungodliness or evil. These, understand. Have no shame in being kindly and gentle, but if the time comes in the time of your life to kill, kill and have no regret. In the time of your life, live — so that in the wondrous time you shall not add to the misery and sorrow of the world, but shall smile to the infinite delight and mystery of it.

§ IV
1910s, At the Feet of the Master (1911)
Context: See what gossip does. It begins with evil thought, and that in itself is a crime. For in everyone and in everything there is good; in everyone and in everything there is evil. Either of these we can strengthen by thinking of it, and in this way we can help or hinder evolution; we can do the will of the Logos or we can resist Him. If you think of the evil in another, you are doing at the same time three wicked things:
(1) You are filling your neighbourhood with evil thought instead of with good thought, and so you are adding to the sorrow of the world.
(2) If there is in that man the evil which you think, you are strengthening it and feeding it; and so you are making your brother worse instead of better. But generally the evil is not there, and you have only fancied it; and then your wicked thought tempts your brother to do wrong, for if he is not yet perfect you may make him that which you have thought him.
(3) You fill your own mind with evil thoughts instead of good; and so you hinder your own growth, and make yourself, for those who can see, an ugly and painful object instead of a beautiful and lovable one.
Not content with having done all this harm to himself and to his victim, the gossip tries with all his might to make other men partners in his crime. Eagerly he tells his wicked tale to them, hoping that they will believe it; and then they join with him in pouring evil thought upon the poor sufferer. And this goes on day after day, and is done not by one man but by thousands. Do you begin to see how base, how terrible a sin this is? You must avoid it altogether.
