The waves of the sea go up and down; the atom believes that they rise and fall for it; it thinks, "The wave raises me, so it is favorable to me", or, "it lowers me, so it is unfavorable." In the same way man thinks a friend is favorable or unfavorable to him; but then he realizes that this is the nature of the world. In all of us there is the Nafs, the ego, and every ego fights against the others. There is a sword in every hand, both in that of the friend and in that of the enemy. The friend kisses before he strikes; there is no other difference. And then he realizes that nothing else can be expected of the world.
