Kundalini Yoga consists of active and passive asana-based kriyas, pranayama, and meditations which target the whole body system (nervous system, glands, mental faculties, chakras) to develop awareness, consciousness and spiritual strength.
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.
