Jnana yoga is the yoga of knowledge—not knowledge in the intellectual sense—but the knowledge of Brahman and Atman and the realization of their unity. Where the devotee of God follows the promptings of the heart, the jnani uses the powers of the mind to discriminate between the real and the unreal, the permanent and the transitory.
Jnanis, followers of nondualistic or advaita Vedanta, can also be called monists for they affirm the sole reality of Brahman. Of course, all followers of Vedanta are monists: all Vedantins affirm the sole reality of Brahman. The distinction here is in spiritual practice: while all Vedantins are philosophically monistic, in practice those who are devotees of God prefer to think of God as distinct from themselves in order to enjoy the sweetness of a relationship. Jnanis, by contrast, know that all duality is ignorance. There is no need to look outside ourselves for divinity: we ourselves already are divine.
What is it that prevents us from knowing our real nature and the nature of the world around us? The veil of maya. Jnana yoga is the process of directly rending that veil, tearing it through a two-pronged approach.
An Unreal Universe
The first part of the approach is negative, the process of neti, neti—not this, not this. Whatever is unreal—that is, impermanent, imperfect, subject to change—is rejected. The second part is positive: whatever is understood to be perfect, eternal, unchanging—is accepted as real in the highest sense.
Are we saying that the universe that we apprehend is unreal? Yes and no. In the absolute sense, it is unreal. The universe and our perception of it have only a conditional reality, not an ultimate one. To go back to our earlier reference to the rope and the snake: the rope, i.e., Brahman, is perceived to be the snake, i.e., the universe as we perceive it. While we are seeing the snake as a snake, it has a conditional reality. Our hearts palpitate as we react to our perception. When we see the “snake” for what it is, we laugh at our delusion.
Similarly, whatever we take in through our senses, our minds, our intellects, is inherently restricted by the very nature of our bodies and minds. Brahman is infinite; it cannot be restricted. Therefore this universe of change—of space, time, and causation—cannot be the infinite, all-pervading Brahman. Our minds are circumscribed by every possible condition; whatever the mind and intellect apprehend cannot be the infinite fullness of Brahman. Brahman must be beyond what the normal mind can comprehend; as the Upanishads declare, Brahman is “beyond the reach of speech and mind.”
Yet what we perceive can be no other than Brahman. Brahman is infinite, all-pervading, and eternal. There cannot be two infinites; what we see at all times can only be Brahman; any limitation is only our own misperception. Jnanis forcefully remove this misperception through the negative process of discrimination between the real and the unreal and through the positive approach of Self-affirmation.
In Self-affirmation we continually affirm what is real about ourselves: we are not limited to a small physical body; we are not limited by our individual minds. We are Spirit. We were never born; we will never die. We are pure, perfect, eternal and free. That is the greatest truth of our being.
The philosophy behind Self-affirmation is simple: as you think, so you become. We have programmed ourselves for thousands of lifetimes to think of ourselves as limited, puny, weak, and helpless. What a horrible, dreadful lie this is and how incredibly self-destructive! It is the worst poison we can ingest. If we think of ourselves as weak, we shall act accordingly. If we think of ourselves as helpless sinners, we will, without a doubt, act accordingly. If we think of ourselves as Spirit—pure, perfect, free—we will also act accordingly.
As we have drummed the wrong thoughts into our minds again and again to create the wrong impressions, so we must reverse the process by drumming into our brains the right thoughts—thoughts of purity, thoughts of strength, thoughts of truth. As the Ashtavakra Samhita, a classic Advaita text, declares: “I am spotless, tranquil, pure consciousness, and beyond nature. All this time I have been duped by illusion.”
Jnana yoga uses our considerable mental powers to end the duping process, to know that we are even now—and have always been—free, perfect, infinite, and immortal. Realizing that, we will also recognize in others the same divinity, the same purity and perfection. No longer confined to the painful limitations of “I” and “mine,” we will see the one Brahman everywhere and in everything.
