Brad, who practices Zen Buddhism and writes about it as well, has a very interesting experience to share:
People long for big thrills. Peak experiences. Some people come to Zen expecting that Enlightenment will be the Ultimate Peak Experience. The Mother of All Peak Experiences.
But real enlightenment is the most ordinary of the ordinary. Once I had an amazing vision. I saw myself transported through time and space. Millions, no, billions, trillions, Godzillions of years passed. Not figuratively, but literally. Whizzed by. I found myself at the very rim of time and space, a vast giant being composed of the living minds and bodies of every thing that ever was. It was an incredibly moving experience. Exhilarating. I was high for weeks. Finally I told Nishijima Sensei about it . He said it was nonsense. Just my imagination. I can’t tell you how that made me feel. Imagination? This was as real an experience as any I’ve ever had. I just about cried.
Later on that day I was eating a tangerine. I noticed how incredibly lovely a thing it was. So delicate. So amazingly orange. So very tasty. So I told Nishijima about that. That experience, he said, was enlightenment.
Brad also wrote about the basic philosophy of Zen Buddhism summed up in one page.
