Emptiness Is Not Vacant Space: From “There Is No Tree” to the Five Aggregates and Liberation

Asking Again Before the Single Character “Emptiness”

I began the live stream by talking about subtitle work. Speech carries tone, facial expression, pauses, and emphasis, but much of that disappears when it becomes text. Classical Chinese translation can strip away word order and voice as well, leaving compressed sentences that resemble codes. That is why I spend so much time correcting captions and rewriting them. We should not assume that recognizing the characters means understanding the meaning; we must recover the question, sequence, and context.

After some conversation with viewers, one person asked, “What does it mean to say there is no fixed essence?” That became the center of the session. Another viewer asked what “live kindly” means, but I postponed that question. Emptiness alone needed the full session because it is central to Buddhism and routinely misunderstood.

“What does it mean to say there is no fixed essence?” Once this is understood, the emptiness of the five aggregates is no longer a mystical formula.

What Emptiness, Emptiness-Nature, Original Nonexistence, and Lack of Self-Nature Point To

The Chinese character for emptiness easily suggests vacant space. That image cannot convey what I mean. Read alongside “original nonexistence” and “lack of self-nature,” its direction becomes clearer: there is no fixed, independent essence existing by itself. The point is not an empty region inside a thing.

I also discussed older and newer Chinese translations. Different characters lead readers toward different pictures. If emptiness is read as vacant space, the wrong explanation begins immediately. If it is read as the absence of fixed essence, the question changes from “What space is empty?” to “What have we mistaken for something fixed?”

Emptiness does not mean vacant space inside matter. It means that the objects and concepts we grasp do not possess fixed self-nature.

The Emptiness of the Five Aggregates Examines Each Aggregate

Form, feeling, perception, formations, and consciousness are the five aggregates, a way of describing the components of a person. To say they are empty is not to call them five empty spaces. It is to say that none of them has fixed essence. The question therefore becomes concrete: does consciousness or recognition possess such an essence, and can anyone take it out and show exactly what it is?

To answer, we must first examine language. A word is not a copy of reality but an abstraction humans created to exchange information. Because a word exists, we imagine a separate fixed thing corresponding to it. Yet words are convenient vessels for concepts, and their contents change across times, places, and speakers.

“There Is No Tree” Does Not Erase the Trees Before Us

I explained the issue with the statement, “There is no tree.” Someone can object that trees are everywhere outside and call the statement nonsense. The objection is understandable. I am not denying the visible organisms. I am saying that the word “tree” contains no eternally identical essence across every time and place.

Imagine early speakers beginning to call certain things trees. People surrounded by conifers, tropical trees, or deciduous forests would not hold identical concepts. As new plants are encountered, boundaries expand or contract: this too will be called a tree, while that will be treated as grass. Asking whether bamboo is a tree already exposes instability in the category.

Can a modern botanist provide an eternal and complete definition? A current scientific criterion may classify most cases, but borderline cases remain and definitions change as knowledge changes. Even people in Korea in 2026 do not carry identical concepts. A father asking his child for a branch to start a fire may imagine a very different thickness and condition from what the child brings.

The word “tree” is useful, but its concept is not an exact and eternal entity. That is what “there is no tree” means.

Concepts Move Across Time, Place, and Person

Language is a social tool for exchanging information. It did not begin with perfect definitions. People grouped roughly similar things, named them, and changed the scope through use. Experts and children hold different concepts in the same era, and one speaker intends different ranges in different situations.

We live effectively through these approximate agreements. The trouble starts when we mistake convenience for essence. We believe the object must have a precise independent boundary because the word exists. Close questioning makes the boundary move. Emptiness does not prohibit ordinary language; it warns us not to grasp language as reality itself.

“There Is No Fish” and the Moving Boundary of Classification

If the tree example is clear, “there is no fish” follows. Where exactly does fish begin and end? Earlier people may have regarded whales as fish, while educated people today do not. A child who has not learned the classification may group a whale with fish by appearance and habitat. Someone then introduces gills as a criterion, and the concept changes again.

Science can offer more precise criteria, but the everyday word never contained an eternal essence. Classification changes with observation, knowledge, and purpose. Living creatures are before us, yet the human way of grouping them as “fish” has no fixed entity. This is the emptiness of a concept.

Then Does Consciousness Have an Essence?

We now return to the aggregates. We use the character for consciousness in words for awareness and recognition. We notice a process of sensing and understanding and call it consciousness. But when pressed to explain exactly what it is, nobody can present it like a distinct object. Changing from Korean or Chinese to Sanskrit or Pali does not solve the problem.

We may roughly call form material, feeling reception, perception a mental image, formations activity, and consciousness recognition. But where does perception end and consciousness begin? What precisely separates feeling from formations? These are useful divisions for describing a person, not five perfectly independent entities. Careful examination shows that each term lacks a fixed range.

The word “consciousness” is useful. Believing in an independent fixed consciousness merely because the word exists mistakes a name for an entity.

Even Death Is Not One Fixed Line

Trying to distinguish consciousness from its absence medically leads to death. Everyone talks as if death were obvious, yet a doctor needs criteria to judge the exact point. Criteria can change across eras and differ among doctors. Medicine and society establish standards because decisions are necessary, but those standards are not an eternal essence of death inscribed in the universe.

Not only tree and fish but life and death, consciousness and unconsciousness share this character. Humans draw boundaries in continuous change and attach names. Names enable communication and judgment; mistaking them for reality begins delusion.

Name-and-Form Is How We Name the World

I approached name-and-form as the problem of names and visible forms. Just as a word for shape extends toward the broader meaning of matter, linguistic content changes. We did not discover the exact name of an already completed entity called fish. We roughly agreed to call creatures like these fish. The same holds for trees and recognition.

People assume that a name and concept guarantee a matching real entity. Saying that the mind hurts can make us imagine a separate thing called mind inside the body. But what can we take out when asked to produce it? Words communicate experience without turning experience into fixed objects. Prajna follows this habit of naming to its roots.

Arising and Ceasing Are Names Attached to Continuous Change

Once names become entities, arising and ceasing look like fixed events. We imagine something emerging from nothing and later vanishing into absolute nothing. Yet when an egg appears or a person is born, an independent thing has not leaped from nonbeing. Conditions and materials gather and change, and we select a phase of that process and call it birth.

Ceasing is the same. No fixed entity disappears into absolute nothing; we mark the end of a form or relation within continuing change and call it disappearance. Thus it is neither truly arising nor truly ceasing. Ordinary words such as birth and death remain useful, but we should not imagine fixed substantial events behind them.

The Wisdom of Prajna Deconstructs Concepts

The Heart Sutra’s wisdom now comes into view. Good and bad, right and wrong, clean and dirty, born and gone move our lives. We become caught in these concepts as though they were reality itself. “I am depressed,” “this is good,” and “I must become perfect” can bind us in the same way. Prajna does not merely ban the sentences; it asks whether what we grasp is truly fixed and independent.

Neither arising nor ceasing, neither defiled nor pure, neither increasing nor decreasing are not isolated mystical formulas. The whole text runs through the dismantling of concepts. When someone claims the highest enlightenment, we ask what “highest” means and how it is known. Investigating the ground of the words we think we understand is the wisdom of prajna.

The alpha and omega of the Heart Sutra is breaking concepts: asking whether what I believe to be an entity really exists that way.

Lack of Self-Nature and the Other Side of Dependent Arising

The absence of essence can also be explained through dependent arising. Nothing exists by itself; everything changes through relationships and conditions. I had discussed this side at length before, so this session focused on language and concepts. They are not separate topics but different approaches to the same issue.

The self is no exception. We vaguely take something to be “me,” but prolonged questioning reveals no fixed core to extract. We recognize something as this within time, space, and relations, while reality does not conform exactly to our names. Expressions such as the emptiness or selflessness of phenomena point toward undoing this reification.

The Nonsense of Explaining Form-Is-Emptiness with Quantum Mechanics

When emptiness is mistaken for vacant space, people explain form-is-emptiness by saying matter is mostly empty. They claim atomic space or quantum mechanics proves the sutra. I criticized this strongly. The Heart Sutra is not teaching physics, nor is it posing a riddle in which vacant space equals matter.

Such interpretations arise because the initial translation and concept were never questioned. Readers see the character, attach their own picture of emptiness, and decorate it with modern science. The sutra asks what I call matter, what I believe myself to be, and what I grasp as right and wrong. Miss that foundation, and memorizing Buddhist terms will not produce understanding.

Breaking One Fixed View Is Liberation

Buddhism from alpha to omega is the breaking of fixed views. If even one fixed view has broken, one is practicing Buddhism. We begin to understand ourselves by observing emotions, preferences, moral judgments, and our whole view of life. Metacognition—seeing what I know, what I do not know, and what I only think I know—belongs here.

Liberation is not a single grand event that permanently removes every concept. Unless we claim to be gods, we cannot claim such perfection. After one attachment is seen and released, another appears. Buddhism is therefore continuous liberation: observing, questioning, debating, and repeatedly noticing what binds us.

Breaking fixed views is liberation. Liberation is not an event completed once, but the process of releasing grasping whenever it is discovered.

Do Not Try to Annihilate the Ego That Appears in Practice

At the end, a viewer said they wanted to study without displaying self-conceit. The commonly used term “image of self” often differs from its scriptural usage, so “ego” or “conceit” may better convey the present feeling. The important thing is not displaying terminology but observing what actually operates within us.

It is natural for ego to arise. We have lived through that operation all our lives, and the goal of making it never arise becomes another attachment. Notice: “It is arising again; I was caught and my mood rose and fell.” Immediate recognition is helpful, but noticing an hour or several days later is still practice. Do not aim at total annihilation; practice noticing sooner.

Even calling Buddhism merely a study of escaping my bondage needs revision. We use our own brain to understand and release delusion, so we must first understand how we operate. When I see how I become bound, I may stop before being dragged to the end. The study becomes alive only when the question is applied to ordinary situations each day. I closed by promising to return to the postponed question about what it means to “live kindly.”
