If the situation was such that there was only one learned lama or genuine practitioner alive, a person whose death would cause the whole of Tibet to lose all hope of keeping its Buddhist way of life, then it is conceivable that in order to protect that one person it might be justified for one or 10 enemies to be eliminated if there was no other way.
Dalai LamaLack of understanding of the true nature of happiness, it seems to me, is the principal reason why people inflict sufferings on others. They think either that the other's pain may somehow be a cause of happiness for themselves or that their own happiness is more important, regardless of what pain it may cause. But this is shortsighted. No one truly benefits from causing harm to another sentient being. . . . . In the long run causing others misery and infringing their rights to peace and happiness result in anxiety, fear, and suspicion within oneself.
