We live conventional life, according to man-made artificial habits and customs. Thus, we wage wars against other nations, kill other humans, animals and plants, and damage our own life system. Essentially, it comes from the fundamental delusion that the self is the most important being to fight any other than the self. There is no absolute independent self in the limitlessly interdependent life system, much less the self to destroy all others. The notion of “self” and attachment to it is the root cause of all problems and suffering. We must awaken to the impermanence, suffering and no-self, three marks of all phenomena (dharma) and live truth life, avoiding the five calamities and attaining the five blisses.
