In the sacrum bone at the base of the spine in every individual there exists a subtle and dormant coil of spiritual energy known as the Kundalini. This energy has been well documented through the ages, and has become a core part of many of the most authoratitive Yoga and spiritual practices. In AD1290, for instance, the renowned Indian saint and mystic Jnanadeva documented in detail the existence of this energy in his seminal treatise on Yoga and the spiritual universe, Jnaneshwari.
