Practicing Patience and Tolerance
Now, there are many, many people in the world, but relatively few with whom we interact, and even fewer who cause us problems. So, when you come across such a chance for practicing patience and tolerance, you should treat it with gratitude. It is rare. Just as having unexpectedly found a treasure in your own house, you should be happy and grateful to your enemy for providing that precious opportunity.
-His Holiness the Dalai Lama
