Nonduality is a term that many folks are not familiar with, but as you may have discovered already in my book or in another one on the subject, it lies at the core of all the world’s wisdom traditions. Nonduality is that forgotten dimension where unity is found in multiplicity, and it is what all the world’s sacred traditions and sages identify as our true nature. Sometimes referred to as the absolute, the invisible, the Divine, or simply suchness, this aspect of our being has no boundaries or divisions, no distinctions between this and that, and no sequence of before and after. Beneath the surface play of phenomena, there is a formless, undifferentiated realm invisible to the naked eye; devoid of all parts, there remains only the unceasing flow and energy of life.

In stark contrast is the reality with which we are all familiar. It is defined by duality; opposition and contrast are everywhere in our ordinary surroundings. Through years of conditioning, we learn to see ourselves as separate and alone in a world of endless divisions, and this delusion of self brings the suffering and meaninglessness so characteristic of the human condition. We are conditioned to see things dualistically, within an either/or framework. Our lives constantly swing between fortune and loss, pleasure and pain, good and evil, and all the other polarities that characterize everyday experience as we know it. This is the realm where we get snarled in traffic, win at tennis, watch our 401(k) go down, and grow old. It sets the stage for the universal spiritual drama, and it is the condition in which we discover our nakedness, self-conscious and separate from everything else. Just as we cannot know hot without cold, or up without down, it is only as individuals alone and vulnerable that we intuit the wholeness that is missing—our true nature. From this moment on, whether we realize it or not, our deepest desire is for this wholeness. It is the state of being we yearn for and the goal of our spiritual quest.

From meditation to mantras, from koans to the Kabbalah, the shared objective of all the great wisdom traditions is clear: all strive to penetrate the conditioning and habituation that blinds us to our true nature. Whether these paths are called mysticism, the way of nonduality, or esoteric spirituality, they find unity where conventional religions see only division and separation. Though separated by centuries, if not millennia, and embedded in cultures that have little in common on the surface, they declare with extraordinary consensus that the world is a seamless whole.

How is one who is new to mystical ideas to grasp the meaning of these words? It might be possible by comparing them to something with which we are already familiar. In this case, metaphorically, a mystic’s realization of wholeness would be like a wave realizing that water is its true nature. This insight would allow the wave to see that the distinctions and boundaries between it and other waves, and the ocean itself, are only apparent. There is nothing but wholeness. The shared identity of all names and forms is a mystical truth that remains deeply buried in the unconscious levels of our being. The fact remains, however, that all is one, and one is all.
