Suppose everybody believed that they had only one eye. We would have to let everybody know that they have two eyes. In the beginning, there would be a lot of people against us, saying that it's not true. Eventually, however, somebody would realize that they actually had two eyes, and then that knowledge would begin to spread. The Shambhala wisdom is actually as stupid or literal as that. It's very obvious. But because of our habitual tendencies and other obstacles, we've never allowed ourselves to believe in it or look at it at all. Once we begin to do so, we will realize that it's possible and true.
