Muladhara is the Sanskrit name for the chakra located at the base of the spine. It is usually represented by the color red. This wheel, or vortex, of pranic energy is said to form the basis of our spiritual development and nourishment. In Kundalini yoga, spiritual energy (or kundalini shakti) is rooted in the muladhara chakra where it sleeps until it is awakened and drawn up the spine. The English name for muladhara is root chakra.
