Again and again, develop compassion for all sentient beings in general, and particularly for those who dislike you. It might be difficult at first, but you will never attain enlightenment as long as you continue to feel ill-will towards your enemies. Those who are now your enemies were in former lives your parents, and there is nothing fixed about the status of an enemy or friend. To feel hostility towards enemies and affection towards your friends is nothing but a deluded form of perception. If you train your mind to recognise everything as insubstantial like a dream, hostility towards enemies will lose its meaning entirely. This is crucially important because ordinarily our lives are driven by the yearning to acquire food and clothing, possessions, partners, status and acclaim. We put a great deal of thought into devising the cleverest, most efficient ways to obtain them, and we think, “So-and-so has this much money, my friends have this much, so I need more.” Or: “In the past, I stayed in this kind of house, in this part of town, but now I shall move to a better place.” We must put a stop to all such thinking.
