Tenzin Gyatso, 14th Dalai Lama Quote
We cannot learn real patience and tolerance from a guru or a friend. They can be practiced only when we come in contact with someone who creates unpleasant experiences. According to Shantideva, enemies are really good for us as we can learn a lot from them and build our inner strength.
