The Ocean-Seal Samādhi
8.2 The Ocean-Seal Samādhi
The previous chapter stretched concentration's lens open once: concentration need not live only in sitting; it can fill one body's whole round of walking, standing, sitting, and lying. This chapter pulls the lens open by another order of magnitude—so large that one person's body can no longer contain it, and its bound must be the whole dharma-realm.
When Part Four read the hundred-and-eight samādhis, there was one name we met only in passing: the Ocean-Seal samādhi—the great sea, wind and waves stilled, printing in one moment the myriad images of the sky. We said then that its home ground is here. The seed is about to flower.
In a Single Thought-Moment, Pervading the Ten Directions
The name "Ocean-Seal" comes, in scripture, from the "Sage's Crown" chapter of the Avataṃsaka Sūtra. Recounting the spiritual power and use of the bodhisattva's samādhis, the chapter has a verse that ties the Ocean-Seal's power directly to the sudden manifestation of "in a single thought pervading the ten directions":
In a single thought-moment it pervades the ten directions … all of this it can manifest—the spiritual power of the Ocean-Seal samādhi.
Two things in this line are crucial. First, what is manifested is all of the "ten directions," not one corner or one object. Second, the manner of manifesting is "in a single thought-moment"—not a sequential traversal but a simultaneous appearing-together within one thought. What the Ocean-Seal samādhi marks is not how fine or how deep the meditator has gathered the mind, but this one matter—making the dharma-realm appear all at once; the spiritual power lies exactly in the sudden manifesting within a single thought.
One key difference between the Ocean-Seal's figure and the common figure of the mirror must be seen clearly. In polishing a mirror to reflect things, what is weighed is mostly whether the reflection is clear, whether it is bright—a purity of degree. What the Ocean-Seal weighs is the wholeness and the simultaneity of what is sealed: the sea's surface does not single out one thing for fine reflection; it raises all images at once into joint manifestation, and that joint manifestation has no before and after. So the Ocean-Seal as a concentration cannot be measured with the ruler of "depth of concentrative power"—what it marks is a structure of the whole appearing together in the present, not a state of mind that can run shallow or deep.
In Each Mote of Dust, Samantabhadra Enters Alike
The Ocean-Seal's most complete scriptural archetype lies not in the "Sage's Crown" chapter, where the name occurs, but at the very opening of the whole sūtra, in the moment the bodhisattva Samantabhadra enters samādhi. The "Samantabhadra's Samādhi" chapter recounts how Samantabhadra enters samādhi at the opening of the assembly; the text gives this concentration its name, and describes the field within it:
This samādhi is named: the Tathāgatagarbha-body of all Buddhas Vairocana … able to display within the dharma-realm the images of the many … the swirling sea of the dharma-realm, none of it not drawn in … the ocean of the wisdom-light of the Buddhas of the three times all arises from this.
Look closely at three senses. First, the name of this concentration is "the Tathāgatagarbha-body of all Buddhas Vairocana"—the concentration is no longer named after a single object as its support (as the kasiṇa totalities are named after earth, water, or fire as their objects) but takes "the treasury-body of the Buddhas," "the sameness-nature of all Buddhas," as its measure. Second, "able to display within the dharma-realm the images of the many," "the swirling sea of the dharma-realm, none of it not drawn in"—what appears within the concentration is the whole dharma-realm, as the sea's surface mirrors the myriad images, as the sea-swirl gathers in a hundred rivers, with no aspect of the dharma-realm left outside. Third, "the ocean of the wisdom-light of the Buddhas of the three times all arises from this"—this concentration is not the passive undergoing of the dharma-realm's reflected appearing; it is the source from which the dharma-realm issues.
And the stroke that follows at once pushes "appearing together" on to "simultaneous in every place":
Of all the motes of dust of this land, within each single mote there are world-ocean-mote-number Buddha-fields … before each Buddha there are world-ocean-mote-number Samantabhadra bodhisattvas, and all of them likewise enter this samādhi of the Tathāgatagarbha-body of all Buddhas Vairocana.
This line is the Ocean-Seal's sharpest doctrinal foothold. It says not only that the dharma-realm appears together within one concentration (the wholeness of space), but that this one event of entering samādhi happens simultaneously within each and every mote of the dharma-realm (the simultaneity of place). The Ocean-Seal's "at once" is double: the myriad images appearing together within a single thought is simultaneity in time; Samantabhadra entering alike within each mote is simultaneity in place.
Concentration is pushed here to an extreme. It is not a stretch of mind that some one person accomplishes at some one place and then maintains—the one who enters this concentration is not "a" Samantabhadra, and what is entered is not "an" object. And so the correlative pairs—the one who enters and what is entered, entering samādhi and leaving it, the concentrator and the state of concentration—all lose their accustomed purchase at the Ocean-Seal: not that they are denied, but that the concentration has been stretched so wide as to gather them all in. The Ocean-Seal is not a concentration occurring at some place within the dharma-realm; it is the dharma-realm's simultaneous mutual identity as a whole, itself presented as a concentration.
The Ocean-Seal's Blazing Manifestation: The Essential Body of the Whole of Huayan
Scripture gave the Ocean-Seal its skeleton and its archetype; the one who forged it into an integrated master-machine of the study of concentration was Fazang, of the Huayan school.
Fazang's decisive step was to rebuild "Ocean-Seal" from a samādhi-name within scripture into "the ocean-seal's blazing manifestation"—a mechanism explaining how the dharma-realm can manifest suddenly and all at once. In the Discernment of the Return to the Source by the Exhaustion of Delusion he fixes its root sense by the great sea:
Delusion exhausted, the mind clarified, the myriad images appear together—just as the great sea raises waves through wind, and when the wind ceases the sea-water clears, and there is no image not manifested. … The forest of forms and the myriad images are sealed by a single dharma.
All three senses are here. The Ocean-Seal is the original awareness of suchness—so the "concentration" of the Ocean-Seal is not a psychological state cultivated into being but the clarifying function of original awareness itself. "Delusion exhausted, the mind clarified, the myriad images appear together"—the Ocean-Seal's power to make the myriad images appear together turns not on applying force in beholding but on delusion exhausted, the mind clarified: as the clearing sea leaves no image unmanifested, so the mind with delusion exhausted seals the myriad images at once. "The forest of forms and the myriad images are sealed by a single dharma"—the reason the myriad images can appear together without obstructing one another is that they are alike sealed by a single dharma, the one mind. The reader will hear a familiar echo: Bodhidharma's "casts off the false and returns to the true," Hongzhi's delusion ended and the native ground appearing again—the Ocean-Seal's appearing-together rests not on a technique of visualization but on a clarified mind-substance.
Fazang then joins the Ocean-Seal to the highest point of Huayan's classification of teachings. Judging the first of the ten profound gates, "the gate of simultaneous complete intercorrespondence," he states outright that what this gate rests upon is exactly the Ocean-Seal samādhi: "This rests upon the Ocean-Seal samādhi. Blazing forth, it is accomplished by simultaneous manifestation." The "simultaneous correspondence, no before and after" of dharma-realm dependent-origination is, for Fazang, not an abstract ontological assertion but tied to a concentration—the dharma-realm's simultaneity is the Ocean-Seal's simultaneity. In the Record of Probing the Mystery he presses this step to its furthest point, establishing "the gate of the ocean-seal's blazing manifestation" and judging: "it is solely by taking this ocean of samādhi as the essential body of this teaching."
The "essential body" is the root on which a teaching stands and from which it issues. Fazang judges the Ocean-Seal to be the root on which the whole of Huayan rests for its simultaneous total manifestation—not one samādhi among the scriptures, but the very concentration on which "Huayan's being Huayan" depends. One thread runs straight down: original awareness; delusion exhausted, the mind clarified; the myriad images sealed by one; simultaneous completeness; the essential body. This is the exact meaning of "concentration's capstone over the dharma-realm": at the level of the classification of teachings, the Ocean-Seal is set in the highest rank, gathering in the whole teaching.
One word of discrimination must be appended here, to hold the line: the phrase so often spoken in Huayan, "infinitely multiplied, endlessly interpenetrating," is a coinage of the exegetes—Fazang, Chengguan, and the like—not scripture of the "Entry into the Dharma-Realm" chapter. In citing it, one should mark it as the exegetes' gloss, and not present it as scriptural text.
Part Eight Is Walked, and a Strange Thing Comes to Light
The Ocean-Seal samādhi has pushed concentration to the very end of its outward reach. It is not the inward road of gathering the mind ever finer, holding the object ever more single; it is the reverse—stretching concentration to be of one measure with the whole dharma-realm: within a single thought the ten directions appearing together, within each mote Samantabhadra entering alike, the forest of forms and the myriad images sealed and manifested at once.
Set this chapter back into the volume's spine, and its place is clear. From the beginning, this volume has been taking one equation apart: concentration does not equal the graded stations of the four jhānas and eight attainments; it is not that single-log bridge of "the longer you sit, the deeper you go, climbing rung upon rung." The earlier parts took it apart from different directions—the Pāli jhāna ladder re-surveyed, Chan gathering concentration inward to the utmost (the living concentration that is amid signs, free of signs), the Lotus spreading concentration across the four postures (concentration-as-conduct). The Ocean-Seal is this spine's last support: it carries concentration outward to the utmost.
And so a strange thing comes to light. Chan's living concentration gathers inward until there is no further in—down to a single thought free of signs; Huayan's Ocean-Seal reaches outward until there is no further out—out to the dharma-realm appearing together. One draws inward to "amid signs, free of signs"; the other extends outward to the dharma-realm's sudden manifestation all at once: two directions exactly opposite. Yet what the two poles jointly witness is one and the same thing: the essence of concentration does not lie in the stations of the four jhānas and eight attainments—it can gather in until there is no further in, and reach out until there is no further out, and be concentration at both. The single thought and the dharma-realm were never apart.
The part of the Lotus and Huayan here comes to its close. The spine closes.
Only—this concentration pushed to its inner and outer poles: where, in the end, is it to return? A mind clarified until the myriad images appear together, a mind unconfused amid signs—its ultimate face, it would seem, is no longer the single pole of "calming." Concentration seems to be pressing itself back to the door of prajñā.
That question the volume's final chapter will answer head-on. Before it, one last stretch of road: concentration walks out of the scriptures and treatises and into the modern world—into the laboratory's EEG, into the monastery's seven-day Chan retreat, into the meditation apps on the phone.
The next part, the Modern Return.
Concentration can be as small as the clearing of a single thought, as large as the measure of the dharma-realm; and its largeness the Huayan marks with a single line—
In a single thought-moment it pervades the ten directions.
