Kundalini is an inner energy dormant at everyone's coccyx. It has the power to push up human's spirit to higher levels, and if we can awaken the Kundalini by right practice, we can not only obtain various kinds of supernatural power which are beyond human's limits, but also attain enlightenment and realization. awakening of Kundalini is the first step to enlightenment and realization.

	The Kundalini reaches the Sahasrara Chakra, rising and penetrating the seven main chakras, or spiritual centers, on its ascent. Once Kundalini is awakened, it rises through the Kundalini's path called Sushumna channel.
	Kundalini lies dormant at the coccyx like a snake coiling itself up.

What is Kundalini? Kundalini is an inner energy dormant at our coccyx; it has a great power and influence over ourselves. In other words, Kundalini is not only a spiritual energy, but a physical energy as well. What happens, then, if Kundalini wakes up from its sleep? It goes up the spiritual channel or path called Sushumna, which runs along our spinal column, to the Sahasrara Chakra in the crown of our head, penetrating the seven main chakras, or spiritual centers on its ascent.
