Kundalini Yoga was brought to the United States from India by Yogi Bhajan. He started an organization called 3HO, which stands for healthy, happy, and holy, to teach the concepts and practices of Kundalini Yoga. Along with the postures there are many meditations in Kundalini Yoga that use Mantras along with Mudras. Mantras are the words recited, and Mudras are the hand positions. In addition, many of the Kundalini meditations use body movements. All the Mantras, Mudras, and bodily movements stimulate specific energy meridians and glands within the body, helping to reawaken dormant energy and creativity.
Kundalini Yoga was originally used in India by the warrior class in the Sikh religion, and then passed on to house holders as a very efficient way to practice Yoga. It has gained great acceptance in the West as it offers great spiritual, physical, and mental benefits through its practice.
