This article maps five distinct types of nonduality, arranged not arbitrarily but according to how deeply they penetrate the structure of experience itself. Each type corresponds to a specific level (or nidana) in the Buddhist framework of dependent origination, moving from the nondual integration of sensory experience down to the root separation that makes experience possible at all. Understanding these distinctions can help practitioners recognize where they are in the process, what to expect next, and why certain teachings refer to certain levels while not touching the deeper levels.

What Is Nonduality?At its most basic, nonduality refers to the collapse of aspects of subject-object separation. In ordinary consciousness, and even witnessing awareness, there appears to be "me in here" experiencing "the world out there." This split feels obvious and unquestionable. Nonduality is a series of progressive realizations that reveal that this distinction (and all distinctions) are constructed by the mind. When the first layer of this is seen through, the boundaries between things start to dissolve.
A Series of Progressive Realizations But here's where it gets interesting. That dissolution can happen at multiple levels. You can recognize the nondual nature of perception while still maintaining conceptual separation. You can see through conceptual boundaries while still believing that consciousness, itself, is nondual. Each time a deeper duality collapses, what seemed like complete awakening reveals itself as partial. The journey continues because awakening has more depth than we imagined was possible. An Integrative Approach Different traditions and contemporary teachers emphasize different aspects (or stages) of nonduality, often without recognizing the other aspects or stages. Most nondual teachings stop at awareness and call it "nonduality". This represents legitimate initial awakening and provides teachings that can benefit the greatest number of people. But awareness (here) observing objects (there) isn't nondual at all. Some of our most advanced teachers stop at perceptual nonduality. This makes compete sense since breaking of the 10 Buddhist fetters and reaching what many people refer to as liberation spits you out in perceptual nonduality, which is a pretty fun place to be. Very few other traditions and teachers (e.g., Bernadette Roberts) point beyond this to experiences that deepen even the most sophisticated nondual teachings. In these deeper stages, the idea of "true nonduality" doesn't even make sense, so let's simply explore the deeper types of nonduality often missed by modern teachers. Each type describes a real and distinct shift in how reality appears. Types of Nonduality at a Glance
Perceptual Nonduality: When the Senses MergeSeeing Through Thoughts & Beliefs
The first major shift occurs at what Buddhist psychology calls salayatana, the six sense bases. In ordinary experience, seeing, hearing, touching, tasting, smelling, and thinking appear as separate channels. You look at a tree, hear a bird, feel the breeze, and these seem like distinct events happening to a central observer. Perceptual nonduality is the collapse of this structure. The six sense doors unify into a single seamless field of experiencing. There's still seeing, hearing, feeling, but from a sort of merged perspective. It's like watching a movie from inside the movie. You experience everything as more of an interconnected hologram. And sight, sound, sensation, all senses are kind of like fluctuating waves on this one lake of experience. The Nonduality of Liberation This is what many traditions point to as liberation or the completion of the Buddhist path of the ten fetters. It's a profound shift. The sense of being a separate self located behind the eyes, looking out at a foreign world, simply stops making sense. Some describe it as everything becoming "just this" or "pure awareness". This stage often brings tremendous relief and a sense that the spiritual search is complete. And in one sense it is. The fundamental illusion of self as separate perceiver has been seen through. But other dualities remain intact, operating below the level of a personal self. Beliefs & Perspectives People in this stage have deconstructed many of their beliefs and perspectives (namely, that the self is any of the content of experience). However, they have not deconstructed the concepts (definitions) that these beliefs were created from. You need a definition of a sandwich to believe in a sandwich. So even when you stop believing in a sandwich, the definition remains. Same is true with the self. You can stop believing that there is a self but your definition of self still seems true. At the stage of salayatana, you have the potential to see through all thoughts, and "transcend" the self. However, thoughts are not the only mental processes creating your reality—they are just the easiest to spot and watch. Almost always when people have the experience of transcending a self, they still hold the belief that the self is something semi-real that can be transcended. And, there is still a definition that the self = thoughts. So 'transcend the self, you must see through thoughts. But this is all still belief and conceptual misunderstanding. If you awaken in the next stage, your definition of self changes, and so there is no longer a self to transcend. You don't have to disidentify from the content of experience because the conceptual structure that made either 'self' or 'thought' seem real dissolves. The Transition If you dissolve salayatana (perceptual nonduality), the six senses unify. You live as "presence" (which is basically living from the senses or beingness). However, there are still 4 more layers of construction underneath this. If you move through the next phase, namarupa (conceptual nonduality), you're dissolving the very mental mechanisms that allow for things to appear as separate units. All units (concepts) collapse and merge, not just the perceptual units (the 5 senses). What Remains Unseen Before This Shift The belief in self has been seen through, yet the meaning-making, concept-making structure that allows beliefs to form has not been seen and dismantled. For example, the spiritual experience of pure, unconditional "love" still seems like a real, blissful experience. The path to the end of suffering still seems like it refers to something real, perhaps a particular set of spiritual insights. "Self" can seem untrue while "no-self" or "ultimate reality" still seem true. Some concepts have dissolved, but all the remaining concepts maintain thier "truth-value". Conceptual Nonduality: When Names and Forms MergeSeeing Through Definitions
The next deepening occurs at namarupa, translated as "name and form." This is where the mind defines undifferentiated experience as discrete objects and concepts. At the perceptual level, there's already unity, but conceptually we still hold onto units of experience that seem real: mediation seems different than 'not meditation'. 'Truth', or 'practice', or 'knowing' seem to be real experiences. We believe these labels correspond to actual, real, separate things. Conceptual nonduality arises when it is seen that the naming function makes it seem like forms are actually real or permanent. There is no actual "thing" that we then label. For example, the word "sadness" doesn't point to a pre-existing emotional experience. The language (and definition) creates the boundary that makes "sadness" seem like a discrete, separable experience distinct from "fear" or "anger" or even "bliss". In reality, experience is not actually broken up into conceptual units. The mind slices experience into categories through language, then mistakes those categories for natural divisions in reality itself. How This is Different from Typical Spiritual Work At salayatana: At the prior stage, you might see that you have a thought about being worthless. You look at the thought, the sensations that are associated with it, and how it creates suffering. With enough witnessing, it becomes clear that it is just a thought (and not the you that observes it) and so it detaches from 'you'. ➟ If you do this for all thoughts, you can greatly reduce suffering. At namarupa: At this stage, you're not witnessing the thought; you're witnessing the units (i.e. concepts) that the thought is made of. In this case, you'd be look at 'worthlessness'. You go all the way into it to see, "What makes worthlessness different from suffering, or helplessness, or even worthiness?" Inside the concepts (like worthlessness, suffering, helplessness, or worthiness), you see that there is nothing actually there. So now, you don't have to detach from thoughts. Since thoughts no longer mean anything, they can arise without causing suffering. ➟ If you do this for all concepts, you can greatly reduce suffering. Research on Conceptual Non-duality Susanne Cook-Greuter's construct-aware stage (in adult development theory) discusses this realization. At this stage the experience of "transcending" the self no longer arises. It's more like what used to seem like the self dissolves into nothingness. Without concepts, there is no self. Concepts don't describe reality. They construct it. ➟In perceptual nonduality (and earlier), each insight feels liberating. You still have the ground of beingness or presence, and you are slowly chipping away at the content that causes suffering. ➟When conceptual nonduality starts to arise, there is a profound sense of groundlessness. The concepts of beingness, presence, and even liberation lose their reality. The Transition When namarupa is seen through (conceptual nonduality), you recognize that all concepts like "self", "presence", and "meditation", are mind-made constructions with no permanent reality. But at this point, the basic dual framework of "sad versus non-sad" or "self versus no-self" still operates. If you move to the next phase, you begin to see the mind splitting up reality into concepts (and duality), thus discovering what made them seem real in the first place. Differential Nonduality: When Distinctions DissolveSeeing Through Distinctions
Deeper still is vinnana, which is sometimes translated as cognition or understanding. More precisely, it refers to the distinction-making function of the mind. This is the mind's habit of differentiating "this" from "that" and thinking that "this" and "that" are actually different. Conceptual Realtionships Versus Distinctions Even though you no longer believe that concepts point to anything real or permanent, they still seem to have relationships with each other. The concept of "meditation" can seem attached to the concept of "effective for awakening" while the concept of "roller skating" seems not attached to the concept of "effective for awakening". This is vinnana at work, making certain things seem related while other things are not related. Certain information is still associated with the concept of "right" while other information is associated with the concept of "wrong". The "sense field" may still be associated with "truth" while "thoughts" are no longer associated with "truth". Thus, THIS (for example, sensations), are still interpreted as different from THAT (for example, thoughts). THIS and OPPOSITE-OF-THIS also seem different. For example, fear and non-fear seem different. These distinctions between THIS and THAT are obviously still a type of duality. Beyond Understanding When vinnana is seen through, teaching, coaching, or answering students' questions no longer works. There is no longer a way for the mind to choose one answer over another—all answers appear to be equally true. Understanding IS the mind choosing one answer or solution over another. When there is no difference between the options the mind can choose from, there is no longer an experience of understanding anything. So, if someone asks you "should I do X or Y to awaken?" you literally can not provide an answer. Both choices are the same. But, this isn't experienced as confusion, because confusion (and all concepts) can not be reliably distinguished from other concepts. Understanding and clarity were never different. Action and non-action were never different. It was always the mind categorizing, making distinctions, and creating relationships between concepts that made them appear to be different. So, THIS and NOT-THIS genuinely don't feel different. Fear and bliss feel the same. Suffering and peace feel the same. Without the mental function of vinnana, there are no real differences. Operational Nonduality: When The Time-Builder DissolvesSeeing Through Mental Linking
At the level of sankhara, often translated as volitional formations or fabrications, we encounter something more fundamental than the collapse of specific concepts or even the relationships between concepts. This is about the constructive mechanisms that create reality or experience. These are the foundational processes that link raw arising and passing of experience into what appears to be a causally connected, temporally ordered, narratively meaningful reality. The illusion of causation is particularly revealing. You watch one billiard ball strike another and the second ball moves. What's actually perceived are separate moments of experience, like individual frames in a film. What strings them together into a causal sequence is entirely mental construction. The interpretation that the first ball caused the second to move, that force or power was transmitted between them, that one event made the other happen, that there's any inherent connection at all beyond temporal sequence, this is added by sankhara. The mind takes "this, this, this, this" and constructs it into "this led to that." The illusion of subtle narrative operates here as well. You will likely have already realized much earlier that narrative (or your story) does not represent actual reality. But, here, it is seen how the narrative got built in the first place. There are these subtle mental mechanisms that tag moments with a location in time and then sew them together, literally like stitches attaching each moment to the next. When this is seen through, now moments no longer seem to be related to past or future moments. The illusion of experience The stitch or link connecting what happened this morning to what's happening now is mentally constructed. It's sankhara weaving raw arisings into seemingly coherent sequences with beginnings, middles, trajectories, outcomes, and implications. There appears to be volition to experience (movement through time) when there is really only 'this, this, this' with links, labels, and meanings attached. This is what makes reality feel like an actual experience over time. Daily Life In daily life, this manifests in ways that can initially feel extremely disorienting. When someone asks why you made a particular decision, the causal story that would normally arise automatically is "I did X because of Y". Now, it is seen that the events happened, the decision happened, but the causal link between them is added explanation (meaning) and not reality. Thus, the "X because of Y" narrative stops arising. So, if someone asks you why you did X, you literally can not answer. The mind can no longer link the two things together. If someone asks you where you would like to be in 5 years (or tomorrow), it's an impossible question. You can not link a 'thought that wants something' to an 'experience in the future'. It just doesn't operate anymore. Work This is when it becomes nearly impossible to hold a regular job. The only reason to reliably do X (work) is because you believe it causes Y (money). But even that is a belief. When living beyond sankhara, the causal belief structure no longer motivates behavior. Behavior still arises—for example, I am writing this article right now—but it's not linked to any sort of outcome or any sort of income. Holding Time Lightly Actions still occur, and language about cause and effect still functions for communication. But there's no belief in these frameworks as real. When you drop a glass and it shatters, you can still say "I dropped it, so it broke," but this is recognized as the illusion of experience, not an account of what's actually happening. Existential Nonduality: When Being and Non-Being CollapseSeeing Through Existence
The deepest level corresponds to avijja, translated as 'not-knowing', pointing to the root condition that makes experience possible: consciousness. Here we encounter the most fundamental duality of all: existence versus non-existence, being versus non-being, consciousness versus nonconsciousness, knowing versus not-knowing—they are all the same thing. Existential nonduality is the collapse of the first separation. It's the direct seeing that existence, itself, arises and falls just like everything else. Consciousness is duality. It is impossible to know, observe, or be aware of anything without duality. Thus, pure nonduality is non-existence. The Illusion of The Present Moment The feeling of there even being a 'present moment' is made up from avijja. We likely wont realize this until existence, itself, begins flickering on and off in daily life. There is literally nothing in the gaps—no consciousness, no observer, no experience, no self, no memory, no nothing. So much for knowing, "I am". In the gap, there is no "I am". In a gap, there is no experience and no existence. We only know that there was a gap by what happens afterwards:
When we see that even existence (or consciousness) doesn't arise consistently, we see that even 'the present moment' is constructed. Consciousness is not the stable, permanent, 'ground' we thought it was. Consciousness is no different than a bubble, a thought, or a rain drop. Here for a moment, and then gone. Disorientation This is very disorienting at first. If you start popping in and out of existence multiple times per day while doing your daily routines, functioning goes right out the window. Not knowing where you are in time and space, not knowing who you are, not knowing what's happening can be really scary and create genuine safety issues while driving, cooking, or navigating other risky tasks. But hopefully, this will only last a few weeks before it starts to intgrate. Disidentification with Existence When existential nonduality begins to stabilize, existence is held lightly. Present moment experience (existence itself) is not seen as ultimately real. You begin to accept that even existence arises and passes away. There is no 'you' that is here and now; there is not even really a 'hear and now'. But it's all fine, and actually quite awe-inspiring. We begin to allow existence, itself, to rise an fall with non-attachment. We begin to enjoy even the play of total destruction and recreation. Nothing exists, but it's no longer scary; it's just...beautiful. Final Thoughts on Types of NondualityThese five types of nonduality—perceptual, conceptual, differential, operational, and existential—map the deepening progression through the structure of experience. Each level reveals what the previous one took for granted. Each collapse of duality exposes a more fundamental division that had been invisible before.
Different people may stabilize at different depths. What's valuable about this framework is that it explains why teachings that made no sense at one stage suddenly become obvious at another. Why someone can experience profound awakening and still sense that something deeper beckons. Why descriptions of realization can seem contradictory when they're actually pointing to different levels of the same process. The journey through these types of nonduality is not about accumulating more experiences or reaching a final destination. It's about the progressive collapse of existence itself. Each stage removes something false. And that removal keeps revealing deeper and deeper layers of fabrication until there is nothing left. |
