"[T]he shaman treats all realities as subjective, much like some modern theoretical physicists are beginning to do. In such a viewpoint the question of whether an experience is real or not makes no sense, because the answer is yes and no, depending on your point of view."

We tend to believe in the modern secular world that if you tell someone something once, they'll remember it. ... Religions go, "Nonsense. You need to keep repeating the lesson 10 times a day. So get on your knees and repeat it." That's what all religions tell us: "Get on your knees and repeat it 10 or 20 or 15 times a day." Otherwise our minds are like sieves.
