The precept of non-violence is a
reminder for us to always try to avoid harming other living beings'
lives as much as we possibly can; so that we don’t intentionally
harm them or have the intention of violence in our hearts.
Wanting to kill and accidentally killing are two
different things. Killing and “killing” are different: It's
not the killing that’s bad; it’s our conscience wanting
to kill that’s bad. It’s bad for us, not for the killed.
So keeping the non-violence precept is good for you, not for any other
being. Because if we lose a physical body, we can get it back again;
so those who kill are the ones who become damaged, not those who are
killed.
Thus the precept of non-violence is actually meant
to remind us to keep a very compassionate, loving heart. We don't want
to harm things intentionally because our intention is what kills. It
kills those things and also kills us, which is very bad.
