The word "compassion" is its accepted sense—which is bad etymology—implies that you are a fine fellow, and the other so much dirt; that is, you insult him by pity for his misfortunes. But "Every man and every woman is a star."; so don't you do it! You should treat everybody as a King of the same order as yourself. Of course, nine people out of ten won't stand for it, not for a minute; the mere fact of your treating them decently frightens them; their sense of inferiority is exacerbated and intensified; they insist on grovelling. That places them. They force you to treat them as the mongrel curs they are; and so everybody is happy!
The Book of the Law is at pains to indicate the proper attitude of one "King" to another. When you fight him, "As brothers fight ye!" Here we have the old chivalrous type of warfare, which the introduction of reason into the business has made at the moment impossible. Reason and Emotion; these are the two great enemies of the Ethic of Thelema. They are the traditional obstacles to success in Yoga as well as in Magick.
Now in practice, in everyday life, this unselfishness is always cropping up. Not only do you insult your brother King by your "noble self-sacrifice," but you are almost bound to interfere with his True Will. "Charity" always means that the lofty soul who bestows it is really, deep down, trying to enslave the recipient of his beastly bounty!
In practice, I begin afresh, it is almost entirely a matter of the point of view. That poor chap looks as if a square meal wouldn't hurt him; and you chuck him a half-crown. You offend his pride, you pauperize him, you make a perfect cad of yourself, and you go off with a glow of having done your good deed for the day. It's all wrong. In such a case, you should make it the request for favour. Say you're "dying for someone to talk to, and would he care to join you in a spot of lunch" at the Ritz, or wherever you feel that he will be the happiest.
When you can do this sort of thing as it should be done, without embarrassment, false shame, with your whole heart in your words—do it simply, to sum up—you will find yourself way up on the road to that royal republic which is the ideal of human society.
Love is the law, love under will.
