各位要注意这个“净”字。净，是什么意思呢？就是不染污，就是清净，丝毫的染污也没有，这种净就是一念不生谓之净，净念。
You should pay attention to the word “pure.” What does “pure” mean? It means being pure and clean, free from all defilement. Not having the slightest defilement is the kind of purity in which not even a single thought arises.
你单在外边持戒，说：“我不杀生。”你心里常常不满意人，或者发人的脾气，这都犯杀戒了。
Not killing includes purifying our thoughts. If we uphold precepts on the surface and claim that we don’t kill, but we complain about others constantly or get angry with people, we are still violating the precept against killing.
偷盗，你不必真正去偷去，就心里面羡慕人家的财物或者技能，妒嫉人，这都犯了盗戒了。
Not stealing includes mental states. We don’t have to steal physically. When we envy other’s wealth or talents, or become jealous of people, we transgress the precept against stealing.
邪淫，你心里尽打异性的妄想，这都叫犯了淫，都是不净了。
Not committing sexual misconduct includes not having improper thoughts about the opposite sex. If we indulge in improper thoughts about the opposite sex, then we are being impure and breaking the precept.
这个净戒，就要乾干净净的，一点染污念也没有了，这才是净戒。
Holding the precepts purely means leading a clean life without any defiled thoughts. That is to hold the precepts purely.
