Once, in a small town known as Red Dove City, there was a homeless drunk who was a retired scholar of philosophy and etiquette who had informed a young, courageous boy who properly learned cultivation and principles from his elder brother that sincerity was best shown in threes.
He told of the three ceremonial bows of a lifetime, where one bows to the bindings of life, the eternal deliverance of death, and the recognition of all things beneath heaven and earth that were blessed upon you.
But most importantly, what stuck with him the most, was the act of giving blessings and displays of love in three, especially when gifting, offering, or requesting things from heaven and earth. It was ravings of a distraught mind once keen and sharp, yet believed with all that drunk's soul, and the young, courageous boy had felt it.
