The Buddha said, “I have looked deeply into the state of mind of unhappy people and have seen hidden under their suffering a very sharp knife. Because they don’t see that sharp knife in themselves, it is difficult for them to deal with suffering.” Your fear is buried deep in your heart, a sharp knife covered over by many layers. That sharp knife is what makes you behave in such an unkind way. You do not see the knife or the arrow in your heart, but it causes you to make other people suffer.
