It is not necessary that this renunciation should be practiced by indifference to one's friends. No, one can love one's friends and serve them, and yet be detached. It is this lesson which Christ taught when he said, "Render therefore unto Caesar the things which are Caesar's, and unto God the things that are God's." He has renounced who gets the things of the world, but gives them to the world; but the one who does not know renunciation gets the things of the world, and holds them for himself. Love is a blessing, but it turns into a curse in attachment; admiration is a blessing, but it turns into a curse when one tries to hold the beauty for oneself.
