Kundalini (kuṇḍalinī, Sanskrit: कुण्डलिनी, Thai: กุณฺฑลินี) literally means coiled. In yoga, a "corporeal energy" - an unconscious, instinctive or libidinal force or Shakti, lies coiled at the base of the spine. It is envisioned either as a goddess or else as a sleeping serpent, hence a number of English renderings of the term such as 'serpent power'. Kundalini awakening results in deep meditation, enlightenment and bliss. The long terminal ‘i’ added to the Sanskrit adjective kundalin, meaning “circular, spiral, coiling, winding,” makes a feminine noun signifying “snake,” the reference in the present context being to the figure of a coiled female serpent—a serpent goddess not of “gross” but of “subtle” substance—which is to be thought of as residing in a torpid, slumbering state in a subtle center, the first of the seven, near the base of the spine: the aim of the yoga then being to rouse this serpent, lift her head, and bring her up a subtle nerve or channel of the spine to the so-called “thousandpetalled lotus” (sahasrara) at the crown of the head.
