In human beings, Shakti, the feminine aspect is called Kundalini. This potential energy rests at the base of the spinal cord. The object of the Tantric practice of Kundalini-yoga is to awaken this cosmic energy and make it ascend through the psychic centres, the chakras, that lie along the axis of the spine as consciousness potentials. She will then unite above the crown of the head with Shiva the pure consciousness. This union is the aim of Kundalini-yoga: a resolution of duality into unity again, a fusion with the Absolute. By this union the adept attains liberation while living which is considered in Indian life to be the highest experience: an union of the individual with the universe.
