Hi there!

Welcome to Simply Nondual. I'm Marcel Eschauzier, a down-to-earth engineer intrigued by nonduality and its profound benefits for well-being and science. I've demystified this timeless truth through my books with clear, accessible language for everyone.

Serene landscape symbolizing nondual awareness through reason

You may have heard of nonduality, but what is it? Every conscious creature is born with the illusion of duality, most without ever realizing it. It seems obvious that human beings exist separately from each other and the rest of the world, and most people take it for granted. But as improbable as it may sound, the perceived separation of our minds and bodies is a mirage. Nonduality is what’s left when this illusion dissipates, and appreciating the nondual is what Zen is all about.

Are Zen and rationality compatible? Many people don’t think so: They either hold that Zen is irrational or that thinking gets in the way of their meditation practice. As a result, nondualism and reason are applied in strictly separate silos, hinging on an imagined conflict between spirituality and science—subjectivity and objectivity. Here, Western thought misses the crucial point of nonduality: Science isn’t predicated on a mind-independent reality—it only seems that way.

Emerging scientific evidence never fails to confirm what Zen monks have known for centuries: The perceived separation between the “subjective” observer and “objective” reality is an illusion. Yet, seeing beyond the illusion of duality, also known as enlightenment, awakening, or satori, is not trivial because it’s deeply counterintuitive.

As a result, much of science remains rooted in dualism, with many scientists still believing that consciousness is a product of the physical brain, vainly trying to conceive a material cause for what is demonstrably preconceptual. Zen involves fathoming the illusion of objectivity, prompting a rediscovery of the four principles of rational thought to sustain scientific and public discourse.

My books are about nonduality and overcoming irrationality. The modern West is less rational than it realizes because of its secular dualistic way of thinking—which is like a religion because it involves faith in the human mind magically crossing over into realms beyond itself. This supernatural belief disconnects the mind from intuition and common sense. In contrast, rational nondualists admit that we fundamentally lack knowledge of a mind-independent reality since the objective is inseparable from the subjective.

Zen and reason combined could lead to a better world and greater personal well-being. Different cultures point at something we all share using varied terminology. Recognizing this through nondual awareness can increase mutual understanding, reduce conflict, and help us connect with our inner truth. Reason serves as a universal language because it taps into our shared human value, even as it is expressed differently.

Well-being

Nonduality is all-pervasive. Trusting it has astounding benefits for your well-being—a message passed on to us by legendary Eastern sages like Lao Tzu, Bodhidharma, Shin-t’ou, and Huang-po. The philosophical guides Oneless Oneness and Awakening the Other Way explain in simple words why their timeless teachings don’t require religious beliefs but merely an inquisitive mind.

Philosophy

It’s easy to overlook nonduality, but you can experience it in simple things. The logical arguments for nonduality are equally straightforward, adding to their impact. But why use the word “nondualism” when modern Western analytical philosophy and metaphysics typically only recognize “dualism” versus “monism”? The essay How to See Consciousness solves this riddle.

Science

No more “reality duality”: Reimagined science embraces the subject-object unity. Some readers seek examples of nonduality impacting science. Here’s one: Science can never reveal what the world consists of, only how it appears to us—and why. This insight disrupts quantum physics interpretations and quantum computing feasibility. How? Find out in the treatise Existential Rationalism.
