Bōrě xīnjīng shū 般若心經疏
Subcommentary on the Heart of the Perfection of Wisdom Sūtra by 慧淨 (作)
About the work
A one-fascicle Heart Sūtra commentary attributed to Huìjìng 慧淨 (b. 578, floruit through the early Zhēnguān era), the early-Tang scholar-monk known to Tang court literati as the “Eastern Bodhisattva” (東方菩薩). Preserved in the Wàn xùzàng 卍續藏 (modern reprint as Xùzàng jīng) as X521. The work is anchored on Xuánzàng’s short-recension Heart Sūtra (T251 = KR6c0128).
The commentary is brief and elegant, written in a balanced piánwén 駢文 style characteristic of early-Tang Buddhist letters. Signature: 「慧淨法師 作」 — “composed by Dharma-Master Huìjìng”.
Prefaces
Huìjìng’s opening preface (“夫以…”) is a model of early-Tang Buddhist parallel prose, shorter than Fǎzàng’s later virtuoso piece (KR6c0139) but in the same exegetical genre: “The True Source is calm and pure, marvellously beyond the surface of name-and-utterance; Right Awakening is profoundly settled, lofty above the entanglements of image and sign. To seek nature and characteristics — the two wisdoms cannot illuminate the True Mechanism; in shallow and deep traces, the three beasts cannot reach the ultimate.” The metaphor of the three beasts (三獸 — hare, horse, and elephant crossing a river to varying depths) is the standard Tiāntái figure for the three vehicles’ incomplete penetration of the Prajñā doctrine, used here to set up the Heart Sūtra’s positioning as the essence of the Prajñāpāramitā corpus.
He then elaborates a five-fold definition of Prajñā — shíxiàng 實相 (true nature), guānzhào 觀照 (true wisdom), wénzì 文字 (true teaching), jìngjiè 境界 (objects-as-realm), and juànshǔ 眷屬 (myriad practices) — adding jìngjiè and juànshǔ to the standard three-mode (Fǎzàng-style) classification. Title etymologisation in the standard early-Tang néngsuǒ 能所 (subject-object) frame: bōrě 般若 is the parent name covering all Prajñāpāramitā literature; xīn 心 (“heart / essence”) is this particular sūtra’s distinguishing designation; jīng 經 is glossed by the canonical four etymologies of chángfǎshèguān 常法攝觀 (“constancy, model, gathering, contemplation”).
Abstract
X521 is the earliest substantial Tang commentary on the Heart Sūtra and the only one anchored unambiguously in the pre-Yogācāra-school doctrinal milieu of the Suí-Tang transition. Doctrinally it draws on Tiāntái 三觀 / 三獸 figures, on the Mahāyāna jiěxíng 解行 frame characteristic of Suí-style scholasticism, and on the earlier Madhyamaka exegesis transmitted through Jízàng 吉藏 (549–623), without yet incorporating the Yogācāra-school trisvabhāva analysis that would dominate after Xuánzàng’s return.
The body of the commentary proceeds line-by-line through the Xuánzàng text. The Heart Sūtra is presented as having only the zhèngzōng 正宗 (main exposition) section without a xùfēn 序分 (preface) or liútōng 流通 (transmission) section, since these are present in the parent Mahāprajñāpāramitā text. The commentary then unpacks each phrase: the five aggregates, twelve sense-fields, and eighteen elements are “characteristically the same as turtle’s hairs — they have only verbal currency, no actual phenomenal characteristic”. The doctrines of the Three Vehicles take the kōng (emptiness) of objects as their contemplative ground; the fan-fu (ordinary man) clings to person and dharma alike; the bodhisattva on the seventh stage realises that all néngchéng (the vehicle-rider) and suǒchéng (the vehicle ridden) are like dream and illusion. The famous figure of the dreamer crossing a river — “as a man asleep dreams of riding a boat across a river to the far shore, and on suddenly waking finds himself in his original place — boat, river, and rider all unreal” — concisely illustrates the Heart Sūtra’s wú zhì wú dé 無智無得 (“no wisdom, no attainment”) through dream-allegory.
Composition date: no internal dating. Huìjìng’s documented activity spans the early Tang (Wǔdé era 618–626 onwards); his major scholarly fame dates from his work on the Sūtrālaṃkāra in 628 and afterwards. The bracket notBefore 605 / notAfter 650 reflects his attested mature floruit; most likely the commentary belongs to the 620s–640s.
The work was unknown to the printed SòngYuán canons and survives only through the Japanese Wàn xùzàng / Manji zoku-zō, which collected it from East Asian manuscript materials.

Other points of interest
The five-fold Prajñā analysis (adding jìngjiè and juànshǔ to the standard three of shíxiàngguānzhàowénzì) is unusual and historically interesting: it represents an expansion of the Sòng-period three-mode classification into a more comprehensive five-mode framework, anticipating the elaborated taxonomies of Tang-Sòng Prajñā scholarship. The dream-and-river figure, while not invented by Huìjìng, is here given an unusually compact and influential formulation.
