Dalai LamaEvery single being, even those who are hostile to us, is just as afraid of suffering as we are, and seeks happiness in the same way we do. Every person has the same right as we do to be happy and not to suffer. So let's take care of others wholeheartedly, of both our friends and our enemies. This is the basis for true compassion.
Dalai LamaIf someone has a gun and is trying to kill you, it would be reasonable to shoot back with your own gun.
