Piyavadana
Usually I distinguish three parts of Buddhism: Buddhist science, Buddhist philosophy and Buddhist religion. Look at the example of Buddha himself. Buddha originally was an ordinary sentient being, a limited being. He taught how to transform our ordinary emotions and minds step by step and, by following that path himself, he finally became enlightened, and that’s a Buddha. Therefore, the Buddhist approach is to start on this level, the level of ordinary people, and then proceed on that level all the way up to Buddhahood.
