In Zen, hallucinations are called makyo. It is not unusual for practitioners sitting in meditation for long periods of time to experience makyo. Some people feel like they are levitating, others see visions of the Buddha bathed in light, some hear sounds or voices. This in itself is not a problem. The problem arises when we confuse these experiences with enlightenment. When students come to me in dokusan to give me elaborate description of their makyo, a common response from me could be something like, “Oh, don’t worry about it—it will go away. Maybe you’re not sitting straight.” In other words, don’t attach to it. But if a dream is real, why isn’t makyo real? Are dreams, makyo, enlightenment and delusion the same, or are they different?
