Definition - What does Kundalini mean?
Kundalini is a Sanskrit term that literally means "coiled one." In spiritual circles, this term represents the primal force that lies "coiled" at the base of one's spine. Yoga poses, controlled breathing and meditation provide a means to awaken the kundalini and channel its enlightening force upward through the seven chakras, to the sahasrara chakra at the crown of the head.
Yogapedia explains Kundalini
Kundalini yoga was introduced to the West in 1969 by Yogi Bhajan, Ph. D. Before that time, this practice was veiled in secrecy and instruction was solely between a master and one chosen disciple. Founder of the Kundalini Research Institute and the 3HO (Healthy, Happy, Holy Organization), Yogi Bhajan strongly felt that this “science of the total self” should be shared with the masses so that they, too, could experience the benefit of the tradition’s teachings.
An intense practice, Kundalini yoga awakens the “coiled” primal life force residing at the base of the spine. Through movement, chanting and meditation, this practice channels the force from the base, upward through the body’s spiritual centers, or chakras. As it is channeled, the force “unblocks” each chakra, awakening energy and freeing the practitioner to experience total health and blissful enlightenment.
