An inner spiritual and sexual energy that resides at the base of the spine but can be stimulated to rise to the crown chakra.

“According to Indian yogis, kundalini is the spiritual energy of complete consciousness. This energy lies dormant in the root chakra at the base of the spine, and can be “awakened” through devout meditation – or sometimes spontaneously – to allow a person to reach enlightenment. The name kundalini is a Sanskrit word meaning “snake” or “serpent power,” because this energy is thought to be coiled at the base of the spine like a snake. …  This powerful, often overwhelming experience brings a person to a higher plane of consciousness.” ( Ashleigh Frank, Kundalini and Spiritual Enlightenment).
