Laya yoga (लय योग), also called Kundalini Yoga, is the practice whereby the Kundalini energy is raised, and which is attainable through deep meditation (dhyana). Laya Yoga helps the aspirant to attain union with the supreme consciousness. If the body is not kept purified both externally and internally through the practices of Hatha Yoga, the succeeding steps of Laya Yoga would yield no result.
