People think that renunciation is learned by unselfishness. It is the onlooker who sees renunciation in the form of unselfishness, as a dog might see renunciation when a man throws away a bone: it does not realize that the bone is only valuable to it and not to the man. Every object has its peculiar value to every individual; and as a person evolves through life so the value of things becomes different; and as one rises above things so one renounces them in life. And when the one who has not risen above them looks at someone else's renunciation, he calls it either foolish or unselfish.
