Franklin Merrell-Wolff continues this series by presenting the fundamental principles of the yoga of knowledge, or jñāna yoga, which is associated with the intellectual mind sheath. He discusses Shankara’s conception of the orders of unreality and concludes that the conceptual order has a reality transcending that of the perceptual order. He goes on to outline the triune nature of man and asserts that jñāna yoga uses the powers of the conceptual aspect of man to master the animal or sensuous aspect of man, and then leads to the self-surrender of that conceptual aspect to the Realization of the transcendent, introceptual being. Wolff enters into a discussion of the discontinuity between a sensual being oriented to particulars and a conceptual being oriented to universals, and he suggests that the story of the descent of the Manasaputra, or “sons of mind,” presented in The Secret Doctrine offers an explanation of this problem. He then describes the steps in the process of self-analysis that a jñāna yogin goes through for the purpose of isolating his true identity. Wolff then affirms that by the bestowal of the transcendental component, a fifth stage of yoga, beyond the fourth stage of self-realization, may be realized wherein one transcends the duality between the universe of objects and the nirvanic withdrawal and becomes a free mover laboring to bring that freedom to all suffering creatures.
