A useful decision or choice is to decide to stop mentally talking about everything and refrain from interjecting comments, opinions, preferences, and value statements. It is therefore a discipline to just watch without evaluating, investing worth in, or editorializing, commenting, and having preferences about what is witnessed. … All thinking, from a spiritual viewpoint, is merely vanity, illusion… The less one thinks, the more delightful life becomes. Thinkingness eventually becomes replaced by knowingness.
