The Muladhara chakra is situated under the Kanda, which is the exact place where the nadis Sushumna, Ida, and Pingala join. This is the fundamental or coccygeal chakra. This chakra nourishes all the other chakras with its sexual energy. The Kundalini is found enclosed within the Muladhara chakra. Four nadis similar to the petals of the lotus flower emanate from this chakra. - Kundalini Yoga: The Mysteries of the Fire by Samael Aun Weor
