Kundalini, the serpent power or mystic fire, is the primordial energy or Sakti that lies dormant or sleeping in the Muladhara Chakra, the centre of the body. It is called the serpentine or annular power on account of serpentine form. It is an electric fiery occult power, the great pristine force which underlies all organic and inorganic matter.
Kundalini is the cosmic power in individual bodies. It is not a material force like electricity, magnetism, centripetal or centrifugal force. It is a spiritual potential Sakti or cosmic power. In reality it has no form. The Sthula Buddhi and mind have to follow a particular form in the beginning stage. From this gross form, one can easily, understand the subtle formless Kundalini. Prana, Ahamkara, Buddhi, Indriyas, mind, five gross elements, nerves are all the products of Kundalini.
It is the coiled-up, sleeping Divine Sakti that lies dormant in all beings. You have seen in the Muladhara Chakra that there is Svayambhu Linga. The head of the Linga is the space where Sushumna Nadi is attached to the Kanda. This mysterious Kundalini lies face downwards at the mouth of Sushumna Nadi on the head of Svayambhu Linga. It has three and a half coils like a serpent.
When it is awakened, it makes a hissing sound like that of a serpent beaten with a stick, and proceeds to the other Chakra through the Brahma Nadi, which is also called Chitra Nadi within Sushumna. Hence Kundalini is also called Bhujangini, serpent power. The three coils represent the three Gunas of Prakriti: Sattva, Rajas and Tamas, and the half represents the Vikritis, the modification of Prakriti.
