Kunalini (kuṇḍalinī कुण्डलिनी) Sanskrit, literally "coiled". In Indian yoga, a "corporeal energy" - an unconscious, instinctive or libidinal force or Shakti, envisioned either as a goddess or else as a sleeping serpent coiled at the base of the spine, hence a number of English renderings of the term such as 'serpent power'. Kundalini is considered a part of the subtle body along with chakras (energy centres) and nadis (channels). The overall conception has many points in common with Chinese theories of acupuncture.
