With the water prayer wheel, the water that touches the wheel becomes blessed. When that water goes into an ocean or lake, it carries the power to purify all the billions of animals and insects there. I have had a wish, which has recently become stronger, to build a prayer wheel in the ocean. Because I have been requested to help with so many other Dharma projects, the idea of making a water prayer wheel had been postponed. However, when I was in the center in Taiwan recently, in a conversation about prayer wheels, I mentioned the idea. One of the benefactors, who has been running the family business for some years, was very happy to make a water prayer wheel because his father had started the business by buying fish. Since the family's prosperity came from fishing, he felt his family owed a lot to the fish, and he already had in mind of doing something to repay or to benefit the fish. When I mentioned the idea of the water prayer wheel, he almost cried, and then he asked, "Why are you telling me to build this prayer wheel?" After I explained the reasons, he was very happy to build a water prayer wheel. I mentioned the idea of building it in the ocean near Taiwan, but he thought to build it in Hawaii where the water of the Pacific Ocean would touch the prayer wheel and bring great benefit.
A fire prayer wheel is turned by the heat of either a candle or an electric light. The light that comes from the prayer wheel then purifies the negative karma of the living beings it touches. It is similar with a prayer wheel turned by wind. The wind that touches the prayer wheel is blessed by the power of the prayer wheel and then has the power to purify the negative karma and obscurations of any being it touches. Because prayer wheels are so powerful in purifying negative karma, I think it is a very good idea to use them. After I explained the benefits of prayer wheel a few years ago at Kopan, Lorna and Terry voluntarily took it upon themselves to make prayer wheels available to other students who wanted to do the practice. They generously made many small prayer wheels and offered them to many students, including me. I then offered mine to the King of Nepal. When I mentioned to him that having a prayer wheel helps when one dies, he suddenly became distant. I think it's not a subject commonly talked about to him. He asked, "Do I have to keep this?" So I said, "Yes."
