The samadhi by which one can transform himself into other living beings is a power of concentration acquired by practice. Such a miraculous phenomenon may sound impossible. However, when we sincerely devote ourselves to the service and welfare of others, we can reach a stage of nonself—real selflessness—and become one with them. In appearance, we may even look like one of them. An adult playing happily with children may look like a child himself. He may feel like a child, too. The children may even consider him to be one of them. Such “transformations” are far from impossible, but they do require a special state of mind. The samadhi by which one can transform himself into other living things is an expression of the Bodhisattva-spirit of devoting one’s self to others. Wonderful-Voice can transform himself into thirty-four bodies. In the next chapter, we meet a famous Bodhisattva with similar abilities.
