The Three Gates of Practice

Zongmi reads the four-gated city as making a precise, limited claim, not a vague gesture toward pluralism: someone approaching from the east cannot simply walk in through the south gate, yet all four gates open onto the identical city inside. The differing methods of practice, in the same way, are genuinely differently suited to differing practitioners — a method fit for one person's temperament is not interchangeable with a method fit for another's — and yet all of them, without exception, terminate in the identical Perfect Enlightenment. This chapter, he notes, is where the sūtra turns from establishing what awakening is to actually supplying the promised methods, and Majestic Virtue Self-Mastery's own name suits the transition: this bodhisattva corresponds to the stage at which the three methods about to be taught have already been perfected and demonic obstruction can no longer disturb the practitioner — majestic virtue describes the perfected power itself, self-mastery describes what it is like to no longer be swayed by what would have disturbed an earlier stage.

Zongmi treats this chapter's three methods as corresponding closely, though not identically, to the Awakening of Faith's own single practice of "true suchness samādhi" — the difference being that the treatise does not divide that one samādhi into three the way this sūtra does. He identifies each method's structure as running through three stages every time: undertaking the practice, the practice bearing fruit, and a corresponding response — and for śamatha, the fruit is a "stillness-born wisdom," the response is the inward feeling of ease that follows genuine stillness, and the mirror simile names what happens once that stillness is fully settled: the practitioner's own mind, quieted, becomes capable of reflecting the tathāgatas the way a still lake reflects the moon, not because the tathāgatas move toward the practitioner, but because a mind no longer agitated by its own waves can, for the first time, actually show what was always there to be shown.

Zongmi unpacks the doubled "illusion" logic here as answering a question this same chapter's method necessarily raises: if the discerning mind, the sense-faculties, and sense-objects are all illusion, how can any of them be trusted to act at all? His answer: precisely because they are illusion rather than real, they can be used without contradiction — one illusion (the practitioner's cultivated skillful means) removing another illusion (the affliction obstructing beings), the way a wooden puppet can still be used to strike another wooden puppet without either being anything more than wood. He reads "that which observes illusion is not itself identical to illusion" as itself immediately undercut by the clause that follows — "since it is not identical to illusion, the observing itself is likewise still illusion" — a compact, two-step move that prevents the observing wisdom from being mistaken for something genuinely real standing outside illusion altogether, matching the same fourfold-release logic already used in Mañjuśrī's and Samantabhadra's earlier chapters. On the growing-seedling simile, he glosses each element: the awakened mind is the seed, the illusion-based method is the soil, the compassionate action that results is the sprout — and once the harvest is gathered, both seed and soil, like the illusion-wisdom and the illusion-actions built on it, are together set aside.

Zongmi reads dhyāna as neither śamatha's stillness nor samāpatti's engagement with illusion, but a third position taking neither pole: not clinging to illusory activity, as the second method's own practitioner still does in a refined way, and not clinging to stillness either, as the first method's own practitioner still does. What remains once both are set down is a "knowing awareness" (無知覺明) that he takes pains to distinguish from mere blankness — this is not an absence of knowing, but a knowing that no longer depends on anything obstructive to know by, which is why body, mind, and world can all remain exactly as they were without the practitioner being caught by any of them.

On the bell-in-its-casing simile, Zongmi records some uncertainty about the exact character the source text intends — he considers three possible readings of a single ambiguous character, settling on the sense of a large bell's ringing tone — but is confident about what the simile as a whole illustrates regardless: a bell's casing and its ringing tone are two different things, the casing staying fixed in place while the sound travels freely outward, unconfined by the metal that produced it. In the same way, the practitioner's ordinary body, mind, and world remain visibly unchanged, exactly where they always were, while the observing wisdom itself moves freely, unconfined by any of them — which is why "affliction and nirvāṇa no longer obstruct one another": both terms name states of the casing, so to speak, while the wisdom itself has already passed beyond needing either term to apply.

Zongmi notes that a bodhisattva need not practice all three methods in equal measure, or even practice each one in isolation — the very next chapter, Eloquent Voice's, exists precisely to work out how they can be combined, one at a time, two at a time, or all three together, into twenty-five distinct configurations. What matters, he stresses here, is only that whichever combination a given practitioner takes up, all three "undertakings" trace back to this same single Perfect Enlightenment, so genuine attainment through any configuration counts as genuine attainment of the whole. On the closing comparison — a single instant's accord with this teaching outweighing the conversion of countless beings to arhatship — he reads it, as in similar comparisons elsewhere in Mahāyāna literature, as measuring depth against breadth rather than devaluing the two-vehicle path itself: bringing beings to a bounded liberation, however vast in scale, remains bounded, while even a single moment's genuine accord with Perfect Enlightenment touches something the sūtra has insisted, from its opening chapter onward, has no boundary at all.

Zongmi notes that the verse restates the three methods purely by their governing similes — mirror, sprout, bell — omitting the fuller three-stage structure (undertaking, fruit, response) the prose spelled out for each, and drops the closing merit-comparison entirely, ending instead on "ultimate nirvāṇa" as the plainest possible name for what all three methods, taken together, accomplish. He treats this chapter's verse as unusually tightly matched to its prose counterpart compared to earlier chapters, precisely because the three similes themselves are already about as compressed as the teaching can get without losing its content.
