I'm not saying that everyone should swim with sharks, but sometimes you have to jump over your own shadow in order to learn something that you will never forget for the rest of your life. Then you know you can conquer your fears.
I firmly believe that all human beings have access to extraordinary energies and powers. Judging from accounts of mystical experience, heightened creativity, or exceptional performance by athletes and artists, we harbor a greater life than we know. There we go beyond those limited and limiting patterns of body, emotions, volition, and understanding that have been keeping us in dry-dock. Instead we become available to our capacity for a larger life in body, mind, and spirit. In this state we know great torrents of delight.
