Awakening of the Kundalini is a major event in the evolution of the soul. There are various methods to awaken kundalini. In fact, most spiritual practices, eventually culminate in the awakening of the kundalini Shakti. Most of these methods have to be learned from a qualified master.
Kundalini Yoga is an esoteric school of yoga which deals with awakening of the inner energy or power dormant in every human being called Kundalini Shakti. The Kundalini lies dormant below the base of the spine, above the Muladhara Chakra or the root plexus. In Yoga and Tantra texts, the kundalini is depicted as a feminine divine power or Shakti that raises up the spine like a serpent to meet the male divine principle called Shiva or Para Brahma.
