The opinions below are not necessarily in alignment with those of The Pure View.
In Tibetan Buddhism, kundalini is called “candali” or “tummo” meditation, and the Dalai Lama, in his writings and teachings, has repeatedly warned Westerners against trying to reach an advanced level before they have done the necessary groundwork. “Meditation on the Completion (advanced) Stage … can be extremely dangerous,” he said in a 1982 interview, “perhaps bringing many types of sickness and even death to the unqualified practitioner.”
Under qualified “teachers” and naive students can be a very dangerous combination in kundalini yoga. This intense meditation technique is symbolized by a snake coiled at the base of the spine. When “awakened,” the kundalini begins rising through seven chakras, or energy points, shattering barriers between the conscious and unconscious mind. Tibetan Buddhist monks call it “tummo” or “candali” meditation, according to Webster’s Online Dictionary, and spend thousands of hours mastering it — but a leading lama equates the Western attitude toward it with spiritual fast food.
