"The coiled creative life force at the base of the astral spine, Kundalini, has always been symbolized as a serpent. When the creative force is “asleep” in delusion, it flows down and outward and feeds all the senses; uncontrolled, its stinging venom causes insatiable lusts. But when the pure Kundalini force is “awakened” by the yogi, it rises to the brain and is transformed into the bliss of Spirit. This uplifting serpentine current is Vasuki, the supreme force for human liberation.
The analogy can be made that God is manifested in the downwardly flowing creative power, kandarpa, which through sex is responsible for the creation of children; and He is also in the uplifting current, Vasuku, which begets the offspring of divine realization."
