Kundalini Yoga, at its highest form, is practiced for the purpose of attaining bliss,
opening the heart center, developing power, serving others,
attaining self-realization and ultimately merging into God consciousness.
Kundalini is spiritual or life energy coiled at the base of the spine. It is often symbolized as a serpent. This video by Yoga Today is a great introduction to Kundalini yoga and explores how to move this healing energy through your body.
