Episode 3 Is Reality a Wave or a Particle? Buddhism & Quantum Physics Can’t Both Be Right

Cold Open

Is light a wave or a particle?

For about 150 years, physicists fought about this. Some experiments showed waves. Other experiments showed particles. It had to be one or the other, right?

Turns out – it’s both. Depending on how you look at it.

And guess what? Buddhism figured this out a thousand years ago. Not about light – about reality itself.

Welcome back to Quantum Awareness. I’m QP short for Quantum Preceptor. And today, we’re diving into one of the most beautiful parallels I’ve ever found between quantum physics and Buddhist philosophy.

Introduction – Setting the Stage

So we’ve covered some heavy topics already. Episode 1, panpsychism – consciousness everywhere. Episode 2, superposition – multiple states at once. Episode 3, karma as a natural law.

Now we’re going to put it all together with something called wave-particle duality.

And I’ve got to tell you, when I first discovered the connection between this quantum phenomenon and thousand-year-old Buddhist teachings, I had one of those moments where everything just… clicks.

You’ll see what I mean.

The Science – Thomas Young’s Double Slit Experiment

Let’s start with the physics. In 1801 – that’s over 200 years ago – a guy named Thomas Young did this experiment that changed everything.

He shot particles – photons of light – at a steel plate with two slits in it. Then he watched what pattern showed up on a screen behind the plate.

If light is particles, you’d expect to see two bright spots – one for each slit. Like if you threw baseballs through two windows, you’d see impacts in two places.

But that’s not what Young saw. He saw an interference pattern – waves! When waves overlap, they create these beautiful rippling patterns. So light must be waves, right?

But here’s where it gets weird.

When Young put a detector at the slits to track individual photons – to see which slit each particle went through – the wave pattern disappeared. Suddenly, he saw particle patterns. Two spots.

The act of observing changed what light WAS.

The Observer Effect Returns

This is the observer effect we keep talking about. But it’s more than that.

Get this: When a single photon was fired, it split into two at the slits, acted like a wave, then reunited as a particle at the screen.

One photon. Displaying qualities of both waves and particles. Simultaneously.

Einstein himself said: “It seems as though we must use sometimes the one theory and sometimes the other, while at times we may use either. We are faced with a new kind of difficulty. We have two contradictory pictures of reality; separately neither of them fully explains the phenomena of light, but together they do.”

Two contradictory pictures of reality that together make the truth.

Hold that thought.

Buddhism – The 3rd Karmapa Weighs In

Now, Buddhism. Not surprisingly,  

has some thousand-year-old insights that compare almost exactly to this quantum phenomenon.

In roughly the year 1320, the 3rd Gyalwa Karmapa Rangjung Dorje wrote his crowning treatise on Mahamudra. He wrote it in poetry – beautiful, cryptic verses.

And listen to this. Verse 6 says:

“The nature of the ground is the dual truth, free from extreme views of a permanent reality and of nihilism.”

Karmapa is saying our reality is the dual truth. Free from any idea of permanent, unchanging existence AND free from the nothingness of nihilism.

Sounds a lot like Einstein, doesn’t it? Two contradictory pictures that both need to be true?

Karmapa: Dual truth – neither permanent nor nothing. Einstein: Dual nature – neither purely waves nor purely particles.

Same idea. Different language.

Verse 11 – The Middle Way of Unity

In case we didn’t catch it the first time, Karmapa clarifies in verse 11:

“May we recognize mind’s essence, which is free of any extremes. It is not existent, for even the buddhas do not see it. It is not non-existent, for it is the basis of everything, of conditioned existence and of the state beyond suffering. This is no contradiction. It is the middle way of unity.”

Read that last part again. “This is no contradiction. It is the middle way of unity.”

What Einstein initially proposed to be a contradiction, Karmapa counters with his conviction that it’s the middle way of unity.

And Einstein eventually agreed! He said separately the theories don’t fully explain light, but together they do.

Thomas Young would agree too. He observed particles splitting, acting as waves, then reuniting as particles once again.

This is a very clearly non-dual, co-emergent reality.

Verse 18 – My Personal Favorite

Now we get to verse 18. This is my personal favorite. Karmapa clarifies once more for the doubters among us:

“Observing phenomena, none is found. One sees Mind. Looking at mind, no mind is seen, it is empty in essence. Through looking at both, one’s clinging to duality naturally dissolves. May we recognize mind’s true nature, which is clear light.”

In complete agreement, Einstein and Karmapa both recognize that a complete, unified understanding of the seen and unseen – the particle and wavelike worlds – between quantum physics and Buddhism leads to the truth of our existence.

And here’s what I find amazing. Young and Einstein were both talking about light. Photons. Waves and particles of light.

And Karmapa? He ends his verse with “May we recognize mind’s true nature, which is clear light.”

Light. It’s all about light.

Non-Duality Explained

So what is non-duality?

In Buddhism, non-duality means reality isn’t split into fixed opposites. It’s not this OR that. It’s not either/or. It’s both/and.

Subject and object aren’t separate. Observer and observed aren’t separate. Wave and particle aren’t separate.

They’re different aspects of the same thing, appearing differently depending on context and observation.

Sound familiar? That’s exactly what wave-particle duality is saying.

Light isn’t a wave or a particle. It’s light. And it shows up as waves or particles depending on how we observe it. But fundamentally, it’s just light – one thing expressing itself in different ways.

The Practical Meaning – What Meditation Reveals

Here’s where this gets really practical.

Meditation helps us see more clearly. Once the veils of our emotions – jealousy, anger, confusion – are cleared away, we see our world free from their constant blurring effect.

Our newly developed wisdom transforms suffering into joy.

Now, think about the double-slit experiment. When the detector – the observer – is turned on, we see evidence of particles. That’s what we normally see in everyday life. The particle nature of things. Solid. Separate. Fixed.

But if we train ourselves in meditation, maybe – just maybe – we can start to see the wave nature too. The possibilities. The interconnection. The fluidity.

Maybe we can understand or even see our consciousness in action. Watch as our awareness interacts with the collapsing wave front into our particle-based, material world.

It sounds crazy, I know. But why not? It might be really amazing.

The Two Paths – Mathematics vs Meditation

So Karmapa, Thomas Young, and Einstein seem to agree on quite a lot.

Maybe the only thing they disagree about is the path. Mathematics versus meditation.

Young and Einstein used experiments and equations to discover wave-particle duality.

Karmapa used meditation and direct observation of mind to discover non-duality.

Do both roads lead to Rome?

I think so. Why not do both? That’s why people like me are here – trying to bridge these worlds.

The Deep Connection

Here’s what gets me. What really gets me.

When Buddhism talks about emptiness, it doesn’t mean nothingness. It means empty of fixed, independent existence.

A wave is empty of being a fixed, solid thing. It’s dynamic. Flowing. Changing.

A particle appears solid but it’s actually empty of independent existence – it’s made of smaller particles, which are made of energy, which is… what? Waves? Vibrations? Information?

The deeper you look, the less solid everything becomes. The more wave-like. The more empty of fixed nature.

Until you realize – like Karmapa said – observing phenomena, none is found. You see Mind.

Looking at mind, no mind is seen. It’s empty in essence.

Through looking at both – the particle nature AND the wave nature, the form AND the emptiness – one’s clinging to duality naturally dissolves.

This Changes Everything

Understanding this – really understanding it – changes how you experience reality.

That person you’re in conflict with? They’re not a fixed, solid enemy. They’re waves and particles. Constantly changing. Empty of fixed nature. Just like you.

That problem you’re facing? It’s not a solid, insurmountable thing. It’s waves and particles. It exists differently depending on how you observe it. How you approach it.

Your own identity? Not fixed. Not solid. Waves and particles. Both and neither. Constantly collapsing and re-forming based on observation and context.

The Path Forward

So where does this leave us?

Einstein and Karmapa, separated by hundreds of years and completely different methods, arrived at the same truth.

Reality is dual. Non-dual. Both wave and particle. Both form and emptiness. Both existent and non-existent.

The answer isn’t choosing one or the other. The answer is holding both. The middle way. The unity.

That’s what meditation trains us to do. Hold the paradox. See both the wave and the particle. Recognize that they’re not contradictory – they’re complementary.

Closing

So waves and particles. They seem to the unlearned – to those of us who haven’t looked closely – to be two very different things.

But when we look deep down the quantum rabbit hole, and when we look deep into our own awareness through meditation, we begin to see how words like “non-dual” and “unity” have a very big place in both the quantum world and Buddhism alike.

The universe is trying to show us something. Through experiments with light. Through meditations on mind. Through poetry and equations and direct experience.

Maybe we should pay attention.

Next time on Quantum Awareness, we’re exploring in our fourth episode Schrödinger’s Cat – and we’re going to ask the question: Was the cat enlightened?

Until then, hold the duality. See the waves AND the particles. And remember – mind’s true nature is clear light.

This is QP. Sound is emptiness, emptiness is sound – and it’s all light. See you next time.
