We usually approach ethical conduct (sila) from either righteousness (morality) or idealism (I must never harm any living thing!) but not often from stability and unification of heart. From the heart we just see what is appropriate to do and do it within the context of connection and nonharm. When we transgress we learn and move on and never expect anything miraculous or perfect in any way. We simply live within the fullness of our humanity, and that is enough.
