What Is Non-Duality? Understanding the Philosophy and Experience

What is non-duality

Non-duality is the understanding that reality is one: that its fundamental nature is consciousness, and that everything arises within that consciousness. Of all the philosophies I have come across, it is the one that makes the most sense of my own experience.

That is the short answer. The rest of this article is an attempt to say what that actually means, which, as you will see, is the hardest part.

A little background

The word comes from the Sanskrit advaita, which simply means “not two.” It is most closely associated with Advaita Vedanta, a school of Indian philosophy that took shape through teachers such as Shankara, traditionally dated to around the 8th century. Similar insights appear across many traditions: in Buddhism, Taoism, and Christian and Sufi mysticism, though each expresses them in its own way. Not all of these traditions describe the fundamental nature of reality as consciousness.

In the 20th century, teachers such as Ramana Maharshi and Atmananda Krishna Menon brought these teachings to a wider audience. Atmananda’s approach is particularly associated with what became known as the “direct path”: rather than years of preparatory practice, it investigates experience directly to see what we really are. Today, teachers such as Rupert Spira, Adyashanti and Eckhart Tolle continue this work in plain, contemporary language. My own understanding resonates most with this direct-path way of seeing.

Knowing it is not the same as living it

For many years I was very interested in idealism, the philosophy that consciousness is primary. I read many books about it. I was fascinated by metaphysics, and idealism made the most sense to me of anything I had read.

But knowing it changed nothing about my experience of the world. It was still an intellectual exercise. Anything can become a mind game in this way. Religion can become a mind game. All philosophy can be a mind game. It stays within the realm of thought, and thought just goes round and round, cycling through slightly different patterns.

Idealism and non-duality are closely related, although they aren’t quite the same thing. One is a philosophical position about the fundamental nature of reality; the other points towards the recognition that reality is not divided into separate things in the way we ordinarily experience it.

Is non-duality a belief? When it is held in the mind, yes. Someone who only understands it theoretically is holding a belief, however sophisticated. When it is experiential, it is no longer simply a belief. It becomes a way of describing an experience: a way of mapping, after the fact and as accurately as possible, reality as it actually appears.

What it is like

The experiential side of non-duality is very hard to describe. In truth, it is impossible. Everything you have ever heard about it is someone trying to describe it: that reality is one, that everything appears within awareness, that awareness is the fundamental nature of all reality, and that you are that awareness. All the words people use are attempts to point at something beyond words.

So the best I can offer is imagery.

Imagine you have lived your whole life in a small box with a loud television playing. Then one day you find a door, step out, and discover a vast, beautiful meadow that never ends. You can still hear the television somewhere behind you, but it is faint and far away. That is the closest I can come to describing it.

Here is another way to put it. Ordinarily, thoughts and feelings can seem to occupy the foreground of experience. They have a certain weight to them. Anxiety, for example, can feel as though it is right there in the centre of your experience, pulling you into it. With non-dual recognition, something shifts. The thoughts may still arise, but they no longer have the same grip. There is a spaciousness around them, and they seem to recede into the background.

Reality without thought, without a sense of self, without an identity clouding it, feels completely different. It feels very light and very spacious. Everything feels alive, tingling, blissful. And the sense of oneness is almost like a new sense of perception, one you didn’t have before. It is as though you can see past the physical and sense what everything is as a whole. Like watching forms and shapes rise up in water, while knowing that everything is arising within the water, and is water.

“If there’s no self, does anything matter?”

This is the question the mind asks, and if it keeps thinking about it, it can spiral, much as anyone can spiral thinking about existential nihilism or any philosophy without inherent meaning.

Underneath the question is fear. When the mind meets the idea that it doesn’t exist as it thought it did, a fear can arise, and it can be enormous. I think fear of non-existence is one of the biggest obstacles to letting go of the ego and seeing through it. The mind says: No, I can’t go deeper into meditation. I can’t sink further into this spaciousness, because I will disappear.

And it is right. It will disappear. What it is wrong about is that it is you.

This is where understanding the philosophy can genuinely help. When you reach that point in meditation and the ego is gripping on, throwing every fear it has at you, you’ll die, you’ll lose yourself, who will look after your children?, a clear non-dual understanding, and ideally someone to guide you, can give you just enough courage in that moment not to give in. You let the ego throw its tantrum, and you allow yourself to sink deeper.

This doesn’t mean forcing yourself through overwhelming experiences. Sometimes the right response is to pause, ground yourself and work with what is arising. Having someone experienced to guide you can be important.

Nor does anything stop mattering. Caring doesn’t disappear. It changes where it comes from. Instead of coming from lack, fear and the need to control outcomes, it comes from fullness, presence and love. You still get out of bed, still work, still love your family. You simply aren’t driven by a self that is trying to get something from life.

“There’s nothing to do”: true or not?

You will often hear non-dual teachers say there is nothing to do: you are already awareness, so meditation and seeking only strengthen the seeker. Whether that is true depends on the level you are speaking from.

From the place of non-dual existence, it is completely true. There is nothing to do, nothing you can do, and everything is just happening by itself. But when working with people, you also have to meet them among the waves. The waves are psychology. Their thoughts, emotions, relationships, fears and identities are where they are experiencing life.

So you meet people at the level of psychology, and you use tools. Meditation is one of those tools. It takes someone from the waves a little deeper into the ocean. Then perhaps they come back up, have another conversation, drop a little deeper, come back up again, have another realisation. “You are already awareness” is true, but it is true from the bottom of the ocean. If every non-dual teacher spoke only from there, they would teach only in silence. That has enormous value, but it isn’t the only way.

Why it matters

This is ultimately why non-duality matters to me. It isn’t simply a different way of understanding reality, or an interesting philosophical position. It changes the way life is experienced. The sense of being a separate individual who must constantly improve, protect and fulfil themselves begins to lose its hold. Life continues, with all its ordinary demands and challenges, but the relationship with it changes. There is less striving, less resistance and a greater sense of freedom, presence and love.

Where to begin

If something in this resonates, the simplest beginning is silence: sitting, letting everything be as it is, and not making it another task for the mind. I have written about this in Silence: The Most Powerful Teacher and Healer.
