Agni Yoga is a synthesis of all yoga paths, particularly Karma Yoga, Bhakti Yoga and Raja Yoga. Agni is the Sanskrit word for Fire, the Creative Fire of the Cosmos, the Fire that is seen in varying degrees at the foundation of all Yogas. As such, it is the Yoga of the coming Fiery Epoch which has been predicted in all the ancient Hindu scriptures. Agni Yoga is also referred to as the Teaching of The Maitreya, the next World Teacher, and the Teaching of the Heart, as it is the Heart Center which is the repository of this Fiery Synthesis of Yogas.
