The difference between human love and divine love is like that between drill and war. One has to drill in order to prepare for war. One has to know the phenomenon of love on this plane in order to prepare to love God who alone deserves love. The one who says, 'I hate human beings, but I love God', does not know what love means; he has not drilled, he is of no use in war. Whether a loving person loves a human being or whether he loves God, he shows no trace of hatred. And the one who has hatred in him loves neither man nor God, for hatred is the sign that the doors of his heart are closed.
