When you stand in your own authority, based in your own direct experience, you meet that ultimate mystery that you are. Even though it may be at first unsettling to look into your own no-thingness, you do it anyway. Why? Because you no longer want to suffer. Because you're willing to be disturbed. You're willing to be amazed. You're willing to be surprised. You're willing to realize that maybe everything you've ever thought about yourself really isn't true.
If to enjoy even an enjoyable present we must have the assurance of a happy future, we are “crying for the moon.” We have no such assurance. The best predictions are still matters of probability rather than certainty, and to the best of our knowledge every one of us is going to suffer and die. If, then, we cannot live happily without an assured future, we are certainly not adapted to living in a finite world where, despite the best plans, accidents will happen, and where death comes at the end.
