Kundalini Yoga

Kundalini yoga is a form of yoga that aims to activate the Kundalini energy, or shakti, that is said to be located at the base of the spine. Kundalini yoga involves chanting, singing, breathing exercises, meditation, and kyrias (sequence of asanas, movement, and breathing exercises that, together, bring specific benefits) and repetitive poses. 
The goal of Kundalini yoga is to increase your level of self-awareness and consciousness. Kundalini energy is often compared to a coiled snake that rises from the spine to the head.
