The antidote to hatred in the heart, the source of
violence, is tolerance. Tolerance is an important
virtue of bodhisattvas [enlightened heroes and heroines]
-- it enables you to refrain from reacting angrily to
the harm inflicted on you by others. You could call this
practice "inner disarmament," in that a well-developed
tolerance makes you free from the compulsion to counterattack.
For the same reason, we also call tolerance the "best armor,"
since it protects you from being conquered by hatred itself.
