The Buddha told us that if we can abide by the precepts and laws, we will have a tranquil body and mind, which will allow us to be free from worries and fear. Deep concentration arises from tranquility. Therefore, the precepts are essential to self-cultivation. If we break the law or the precepts, then our conscience will be plagued by guilt even if no punishment is meted out. Moreover, even if we avoid worldly retributions, there is no way to avoid our karmic retribution. When our body and mind are disturbed, we cannot concentrate on our practice. To practice successfully, we need to be tranquil. It is said, “Precepts or self-discipline lead to deep concentration, from which wisdom arises”.
