Four Categories and Seven Elements: All Dharmas Are Originally the Tathāgatagarbha
6.4 Four Categories and Seven Elements: All Dharmas Are Originally the Tathāgatagarbha
The One Who Notices That You Are Seeing
At the end of the previous chapter you were standing before an experiment you could try at once—close your eyes, and watch yourself seeing.
The ten demonstrations of seeing spent nine rounds doing one piece of work: leading you to recognize the seeing-nature out from the objects of sight. Good. But the story does not end there.
The moment you finally realize "I am seeing"—notice this—who is the one who just noticed that you were seeing?
You might say: that is my mind. Very well—where is your mind? Two chapters back we already searched: the seven locations were combed through, and the mind is not in any of them. You might say: that is some deeper awareness. Very well—that deeper awareness, did your eyes produce it? Did light bring it? Was it already there, sitting in empty space?
From the end of fascicle two through fascicle three, the Śūraṅgama Sūtra pushes this question all the way to its limit. The Buddha no longer discusses only the seeing-nature. He lays out every dharma there is—your body, your feelings, your thoughts, your eyes, the colors you see, your consciousness, even earth, water, fire, wind, and space—and within each one He points out the same single thing:
These dharmas are originally neither caused by conditions nor arising from a self-nature—they are the marvelous true suchness of the tathāgatagarbha.
From the Seeing-Nature to All Dharmas
This sounds a great deal like the Heart Sūtra's "illuminated the emptiness of all five aggregates." The intuition is right, but the direction is different.
The Heart Sūtra is the Prajñā reading—it empties your attachment to the five aggregates. The emphasis falls on emptiness. The Śūraṅgama is the tathāgatagarbha reading—the nature of the five aggregates has always been the tathāgatagarbha. The emphasis falls on original suchness.
These two readings do not contradict each other. One removes what is false (emptying the parikalpita, the universally constructed); the other points out what is true (revealing the pariniṣpanna, the perfectly accomplished nature). The "emptiness" the Heart Sūtra speaks of and the "suchness" the Śūraṅgama speaks of are two sides of one coin. But what the Śūraṅgama gives in this passage is not the answer of "emptiness"—it is the answer of "suchness."
The Buddha employs four classification systems plus seven fundamental elements—the five aggregates, six entrances, twelve sense-fields, eighteen elements, then earth, water, fire, wind, space, seeing, and consciousness—laying every dharma out exhaustively on the table. Not for the sake of classifying. For the sake of letting you confirm, personally, within each category: nowhere can you find an independently existing "thing," yet nowhere are you apart from the marvelous true suchness of the tathāgatagarbha.
The previous chapter led you to recognize the seeing-nature. This chapter lets you see: the seeing-nature was only the entrance—all dharmas are the same.
The Five Aggregates: Five Analogies
The Buddha uses five analogies to take apart the five aggregates one by one—form, feeling, perception, formations, consciousness.
Form aggregate—staring until the eyes produce fatigue. You take clear eyes and gaze at a bright, open sky; you gaze long enough, holding your eyes still and fixing your stare, and floating patterns begin to appear in the sky. Those patterns are not anything truly present in the sky, nor are they anything that came out of your eyes. The form aggregate works exactly like this—what you take to be a solid material world is in fact a "fatigue-of-staring": an appearance that shows up on the originally pure tathāgatagarbha because of fixation.
Feeling aggregate—rubbing the two palms together. Your body was perfectly fine to begin with, with no sensation at all. For no reason you rub your two palms together in empty air—and roughness, smoothness, cold, heat, all sorts of sensations come welling up. These sensations did not come from the air, nor were they hidden inside the palms. Every feeling of pleasure and pain works the same way.
Perception aggregate—hearing someone speak of sour plums. Someone talks to you about sour plums, and your saliva flows. Someone describes the edge of a precipice, and the soles of your feet tingle with apprehension. The plum is not in your mouth, the cliff is not under your feet—but the body's response is real. The perception aggregate "interpenetrates" in just this way: the channel between thought and body can be set off without any real object at all.
Formations aggregate—the waves of a violent torrent. A rushing current, its waves following one upon another, never once breaking off—yet it is not born out of empty space, nor is it something the water itself was bound to do. The formation aggregate is this hidden current: your will, your impulses, your habitual reactions, the former thought pushing the latter, faint and hard to detect, never resting.
Consciousness aggregate—the piṅgala vase carried full of space. Someone takes a vase, stops both its openings, fills it with "space," and carries it a thousand miles to deliver to another land. He thinks he has carried away the space from over here—but space was never short a piece because of the vase, and never gained a piece when it was poured out. The most upside-down thing about the consciousness aggregate is exactly here: you think there is a "my consciousness" doing the knowing of all things—but that "space sealed inside the vase" was never truly sealed in at all.
Five analogies, five modes of delusion. The conclusion is completely identical: originally neither caused by conditions nor arising from a self-nature. This does not mean the five aggregates do not exist—it means their mode of existence is neither manufactured by outer conditions (not by conditions) nor sprung up independently on its own (not from a self-nature). Then what are they? Manifestations upon the marvelous true suchness of the tathāgatagarbha.
Six Entrances, Twelve Sense-Fields, Eighteen Elements—The Resolution Climbs Layer by Layer
The second layer of the four categories is the six entrances—the six faculties of eye, ear, nose, tongue, body, and mind. The five aggregates spoke of what you experience; the six entrances take one step further in—they speak of what you use to do the experiencing.
The one most worth pausing over in this layer is the sixth entrance—the mind-entrance. The Buddha's description is precise to the point of taking your breath away: when weary, one sleeps; when sleep matures, one wakes; surveying sense-data, one remembers; losing memory, one forgets. Tired, you sleep; deeply asleep, you wake again; passing through things, you remember them; after a while, you forget—these arisings and ceasings between waking and sleeping, between remembering and forgetting, are what you call the "knowing faculty of mind." But apart from the arising and ceasing of waking and sleeping, apart from remembering and forgetting, this "knowing nature" has no substance of its own at all.
Part III spoke of how the sixth consciousness is the only one that can look in the mirror—and its instrument is the mind-faculty. Here the Śūraṅgama tells you: even that "able-to-look-in-the-mirror" instrument is itself a fatigue-appearance upon the tathāgatagarbha.
The twelve sense-fields and eighteen elements open out one layer further still—faculty plus object, then faculty plus object plus consciousness. The Buddha breaks each one down with the same logic: you cannot find a "location" where color and seeing truly meet; you cannot find an "element" where consciousness independently arises. The faculty does not produce the object, the object does not produce the faculty, and neither side has a location; consciousness does not arise from the faculty, nor from the object, nor from the two of them combined.
Four layers running all the way down, the resolution of the analysis climbing higher and higher—and yet the fewer "independently existing things" are found. This is precisely the design of the teaching: you assume that analysis will turn up the materials that construct all dharmas, but analysis carried to the end turns up the tathāgatagarbha.
The Seven Elements and the "Originally Pure by Nature" Formula
Having finished the four categories, the Buddha switches to a completely different framework—the seven elements: earth, water, fire, wind, space, seeing, and consciousness.
The first five elements are the basic elements of the material world; the last two—seeing and consciousness—pull awareness and cognition in as well. Notice the intent behind this arrangement: the tathāgatagarbha is not only in matter, and not only in mind; it pervades both sides, and the two sides are connected.
Here appears the core formula of this whole passage of scripture, surfacing complete in the conclusion of every one of the seven elements, seven times in all:
Originally pure by nature, pervading the dharma-realm; following sentient beings' minds, corresponding to what they know; manifesting according to their karma.
Five phrases, taken apart one by one:
Originally pure by nature—the intrinsic state of the tathāgatagarbha. Not made pure through practice, but pure to begin with. Not something that turned this way later, but something that was so from the start. This answers the Heart Sūtra's "neither defiled nor pure"—it was never once contaminated, and so it never needs to be "purified."
Pervading the dharma-realm—there is nowhere the tathāgatagarbha does not reach. It is not present in some places and absent from others. Earth, water, fire, wind, space, seeing, consciousness—all of them are within the tathāgatagarbha, and all of them are the tathāgatagarbha's manifestation.
Following sentient beings' minds—the crucial turn. Although the tathāgatagarbha is originally pure by nature and pervades the dharma-realm, it does not "sit there statically." It follows sentient beings' minds—following different minds, it manifests different appearances. Whatever conditions your mind holds, that is the kind of world the tathāgatagarbha manifests.
Corresponding to what they know—the way of "following." Not a manifesting at random, but a manifesting that corresponds to your "scope of knowing"—your cognitive capacity and range determine what you are able to see. The world an ant sees and the world a person sees are not the same—not because there are two worlds, but because the "scope of knowing" differs.
Manifesting according to their karma—the more concrete mechanism. Following karma—along the tracks of karmic force. Your past actions, thoughts, and habitual reactions determine what kind of world the tathāgatagarbha "manifests" before you.
Five phrases composing one complete account of how the tathāgatagarbha manifests: essence (originally pure by nature) → scope (pervading the dharma-realm) → motive force (following sentient beings' minds) → mode (corresponding to what they know) → mechanism (manifesting according to their karma).
Each Dharma True and Constant in Its Own Body, Each Dharma Interpenetrating and All-Pervading
Why, after the four categories, do we still need the seven elements? Had they not already been exhausted?
Jiāoguāng Zhēnjiàn's classification gives a key insight here.
The argumentative structure of the four categories is this—within each category, it points out that the dharmas that category subsumes are "originally neither caused by conditions nor arising from a self-nature," and that their nature is the tathāgatagarbha. This is subsuming phenomena into principle: gathering concrete phenomenal appearances back into the fundamental principle-body. The result is "each dharma is true and constant in its own body"—the very body of each dharma is true and constant.
But the four categories have not yet accounted for the relationships among these dharmas with one another.
The seven elements break through this limit. They do not only say "the earth-element is the tathāgatagarbha"—they say the earth-element is "originally pure by nature, pervading the dharma-realm." Each element pervades the dharma-realm—earth pervades all places, water pervades all places, fire, wind, space, seeing, consciousness, not one exception. They are not seven things each occupying its own corner; they are seven aspects of the one single tathāgatagarbha.
This is the upgrade from "each dharma is true and constant in its own body" to "each dharma interpenetrates and pervades all." The four categories tell you that each dharma is itself true; the seven elements tell you that each dharma is not only itself true but pervades all places and contains all places. From a point to the whole panorama.
The Astronaut Looking at Earth
This passage of teaching can be grasped through a contemporary analogy (⚠️ a heuristic analogy, not a theoretical equivalence)—
Imagine you are an astronaut, looking at Earth from space.
Seen from outside, Earth is one complete sphere. Everything is happening on it—typhoons, earthquakes, tsunamis, the rise and fall of civilizations—but Earth as a whole neither gains nor loses. A volcanic eruption reshapes the look of the surface, but Earth has not "lost a piece"; an ice age covers the land, but Earth has not "gained a layer."
Now switch the perspective: you are standing on Earth's surface. You are one person caught in an earthquake. The ground heaves, life and death hang in the balance, the four elements churn beneath your feet—from where you stand, everything is in violent flux.
What the four categories and seven elements do is exactly this switch of perspective. You have been standing on "Earth's surface" the whole time, looking out—the five aggregates, six entrances, twelve sense-fields, eighteen elements are everything you experience on the surface as "the ground heaving." What the Buddha wants you to see is the perspective of "looking at Earth from space": the totality of all dharmas has always been the marvelous true suchness of the tathāgatagarbha—originally pure by nature, pervading the dharma-realm. All the arising and ceasing, the coming and going you live through on the surface is, from that perspective, like weather on the Earth—intense, but it does not change Earth itself.
⚠️ But the analogy has to be set down right here. Earth is a bounded physical object—it had a time of formation, and it will in the end be swallowed by the sun. The tathāgatagarbha has no boundary—"pervading the dharma-realm" is not one large sphere, but the absence of any division of inside and outside. An observer on Earth can leave the Earth; but within the tathāgatagarbha you cannot find an "outside" to stand in—because the very act of "standing and searching" is itself inside the tathāgatagarbha.
Three Places Easy to Misread
The teaching of the four categories and seven elements goes off the rails most easily in three places.
"Originally a Buddha, so why practice?" This is the most common misreading. The five aggregates are originally the tathāgatagarbha—since everything already is, then I am already a Buddha. This equates "endowed by nature" with "manifested by nature." A seed buried in the soil is not the same as a flower already in bloom. The second half of the formula is the key—"manifesting according to their karma." You are originally the tathāgatagarbha, but you are at present in the state of "staring until fatigue arises"; the clear sky has been there all along, and yet what you see is wild flowers dancing. Practice is not "creating" the tathāgatagarbha; it is ceasing to stare.
"Isn't this just the ātman of the Brahmins?" Originally pure by nature, pervading the dharma-realm—it sounds extremely like the non-Buddhist ātman, the divine self: a pervasive, unarising and unceasing, pure entity. In the Laṅkāvatāra Sūtra the Buddha clarified this in person: "When I speak of the tathāgatagarbha, it is not the same as the ātman spoken of by non-Buddhists." The difference lies in the second half of the formula. The ātman is a self-existing, permanently fixed entity that depends on no condition whatever; the tathāgatagarbha is not a "thing"—its manifesting is "according to conditions." It has no fixed "appearance of its own"—what it manifests before you depends on your karma and your cognition. The ātman is an object that can be "found"; the tathāgatagarbha is not—the very act by which you search is itself within the tathāgatagarbha. This distinction must be held firmly.
Does "originally not by conditions" deny dependent origination? No. The Buddha is not saying that all dharmas do not arise from conditions—that would directly overturn the twelve links of dependent origination. He is saying: if you take "conditions" as the final explanation—if you suppose that all dharmas are "merely" combinations of conditions—then you have left out the dimension of the tathāgatagarbha. "Not from a self-nature" works the same way—it is not denying that things are as they are; it is saying that if you see all dharmas as some kind of independent existence that "sprang up on its own," then you have turned the tathāgatagarbha into the non-Buddhist concept of inherent nature. The double negation points toward the Middle Way: it can neither be reduced to a product of conditions, nor be understood as a self-existing entity needing no conditions.
Ānanda's Great Vow
When the four categories and seven elements have been spoken, the response of Ānanda and the great assembly is itself part of the teaching—
Each member of the great assembly knew for himself that his mind pervaded the ten directions, and saw the ten directions of space as if viewing a leaf held in the palm of his hand.
The mind pervades the ten directions. The whole perspective has flipped over—no longer "I am inside the world," but "the world is inside the mind." This body born of father and mother, under this perspective, is like a single mote of dust in boundless space, like one bubble in a vast ocean.
Ānanda then made a great vow: "If a single sentient being has not yet attained Buddhahood, I will never enter nirvāṇa."
But right after, he added one more line: "I pray you further examine and remove the subtlest delusions."
He knew he had understood—and he knew, too, that understanding is not the same as realizing. The subtle delusions remain.
The four categories and seven elements draw the inner three chapters of the Śūraṅgama Sūtra to a close—the seven locations searching for mind broke open the question of where the mind is, the ten demonstrations of seeing recognized the seeing-nature, and the four categories and seven elements gather every dharma into the tathāgatagarbha. From "the mind is not there" to "the seeing-nature is here" to "there is no dharma that is not so"—the perspective has expanded, step by step, all the way to its limit.
But Ānanda's line about "subtle delusions" leaves a real question standing: between knowing it, and living it out, what is in the way?
The way home is not a single road. In the next chapter, twenty-five great ones will each show their own road.
Where is your door?
