Let us see in what lie the similarities and differences between Agni Yoga and the preceding Yogas. Karma Yoga has many similarities with it when it acts with the elements of Earth. But when Agni Yoga possesses the ways to the realization of the far-off worlds, then the distinction becomes apparent. Raja Yoga, Jnana Yoga, Bhakti Yoga are all isolated from the surrounding reality; and because of this they cannot enter into the evolution of the future. Of course, an Agni Yogi should also be a Jnani and a Bhakta, and the development of the forces of his spirit makes him a Raja Yogi. How beautiful is the possibility of responding to the tasks of the future evolution without rejecting the past conquests of spirit!”
