3.  The Life Force rising from the base of the spine, the Muladhara chakra, and animating the body, our sexuality, the etheric body, and passing through the chakras to join with its opposite force descending through Sahasrara chakra to open our higher consciousness.

Kundalini manifests as a transforming force centered in the Base Chakra and operating within the body and driving evolution, desire, sex drive, growth, and individual development. It exists on all planes in seven degrees of force.

Bringing astral experiences into conscious (physical brain) awareness requires some arousal of Kundalini and its movement through other chakras whether deliberately or spontaneously.

4.  An energy that is said to reside at the base of the spine. Awakening the Kundalini is one aim of Tantric and Yogic practices. Kundalini literally means coiled, and it also has the implication of a pot. One way to understand Kundalini is to think of it as sexual energy. Another approach would be to define it as the life force that resides within all human beings.
