One of the most basic precepts in Buddhism is to not harm any living being. The Buddha showed us how. Once we begin to rein ourselves in by living morally, we will commit fewer wrongdoings. In this way, we will be less plagued by guilt. We will react less from emotions and more from reason. Harming others less will result in our worrying less. By not wasting time worrying, our minds will be more at ease, and we will be better able to focus on what we wish to: perhaps on our spiritual practice or simply on what we are doing.
As we progressively become calmer, our concentration will enable us to touch our innate wisdom. This is the wisdom that the Buddha experienced and then spoke of. It already lies deep within each of us. But we have yet to enter, much less function from, this clear, intuitive wisdom.
As caring members of society, it is our responsibility to practice the virtues of harmlessness, compassion, and equanimity. These virtues lie deep within us, within our true nature. This true nature is the same as that of all Buddhas. The true nature of Buddhas—their very essence—is loving-kindness, altruism, and tranquility. These qualities lie at the core of their being, and ours.
