Kundalini is derived from a Sanskrit word meaning either coiled up or coiling like a snake, the potential form of Prana or life force.
It is a latent reservoir of psychic energy, which can be awakened and activated by spiritual disciplines. How this awakening takes place is still a mystery to many and much sought after. As the inner Kundalini is awakened, it uncoils and ascends like a snake; which is why it is referred to as ‘Serpent Power’.
Unfortunately this serpent image may serve to play up an alien nature of the energy.
Hence, it is more useful to see Kundalini as the very foundation of our consciousness, for when it moves through our bodies our consciousness also changes with it. Viewed from a purely psychological perspective Kundalini is a rich source of psychic or libidinous energy.
