Kundalini represents the cosmic vital energy lying dormant in the human body, coiled around the base of the spine, like a serpent, asleep...

It describes the dangers and difficulties of the spiritual path and the intense pressure it can exert on the physical body. The practice involves classic poses, breath, coordination of breath and movement, meditation.
