Subcommentary on the Heart of the Perfection of Wisdom Sūtra by 智圓 (述)
About the work
A one-fascicle Northern Sòng Tiāntái commentary on the Heart Sūtra (Xuánzàng’s short-recension version, T251 = KR6c0128), composed by Gūshān Zhìyuán 孤山智圓 (976–1022), the leading Tiāntái master of the Shānwài 山外 wing. Preserved in the Wàn xùzàng / Manji zoku-zō as X529. The signature reads 「孤山沙門 釋 智圓 述」.
Prefaces
The opening preface (「夫至道無名…」) is a mature Sòng-period parallel-prose meditation on the structural relation between the great Mahāprajñāpāramitā (200,000 stanzas) and its essence-extract the Heart Sūtra (14 lines): “The supreme Way is nameless, but without naming there is no way to express its Way; True Emptiness is wordless, but without speaking there is no way to recognise its emptiness… the broad and the brief mutually subtend, the one taste returns to the same end. As for sweeping aside the multitude of doubts and opening up the right principle — it is not only that we see form and emptiness as not-two, but also that we know the equal originality of sentient beings and Buddhas, with no before-or-after to be chased.”
Zhìyuán then announces his methodology: 「敢卛台崖教門龍樹宗趣」 — “I dare to follow the doctrinal gate of the Tiāntái Cliff (= Tiāntái-school doctrine) and the essential aim of Lóngshù 龍樹 (= Nāgārjuna)” — a characteristic Tiāntái-Madhyamaka pairing that places the Heart Sūtra commentary at the intersection of the school’s two principal Indian doctrinal authorities.
Abstract
X529 is the principal Northern Sòng Tiāntái commentary on the Heart Sūtra and a primary document for the Shānwài doctrinal position within the Sòng Tiāntái Shānjiā / Shānwài controversy. The commentary follows the standard Tiāntái wǔzhòng xuányì 五重玄義 (“five-fold mystical meaning”) frame: míng 名 (name), tǐ 體 (essential substance), zōng 宗 (essential thesis), yòng 用 (functional use), and jiāo 教 (doctrinal classification). The Heart Sūtra is analysed as: name = fǎyù wéi míng 法喻為名 (combined dharma-and-metaphor naming); substance = yùnkōng wéi tǐ 蘊空為體 (emptiness of the aggregates); thesis = yuánzhào wéi zōng 圓照為宗 (interpenetrating contemplation); function = dùkǔ wéi yòng 度苦為用 (crossing-over from suffering); and classification = Dàshèng wéi jiāo 大乘為教 (Mahāyāna as doctrine).
The line-by-line explication then elaborates each phrase of the Heart Sūtra in Tiāntái-school doctrinal vocabulary, drawing on Zhìyuán’s deep familiarity with the Lotus Sūtra commentary tradition (Zhìyǐ’s Fǎhuá xuányì 法華玄義 and wénjù 文句) and on Nāgārjuna’s Dà zhìdù lùn 大智度論. The treatment of 色即是空 and 空即是色 in particular invokes the yuánróng sāndì doctrine but with a Shānwài-style emphasis on the guānxīn 觀心 application — a contemplative-mind reading rather than the Shānjiā-school xìngjù (inherent inclusion) ontological reading.
Composition date: Zhìyuán’s own Bōrě xīnjīng shū yímóuchāo 般若心經疏詒謀鈔 (X530 = KR6c0149), composed Tiānxǐ 1 (1017), retrospectively notes that he composed the present shū “in a single day” before producing the chāo sub-commentary; the shū therefore predates the autumn of 1017. The bracket notBefore 1010 / notAfter 1017 reflects this.

Other points of interest
The pairing of Tiāntái doctrinal authority and Nāgārjuna in the preface is significant: Sòng Tiāntái was reasserting its descent from Nāgārjuna against the Huáyán and Chan schools’ competing patriarchal claims, and Zhìyuán’s commentaries consistently emphasise this. The Heart Sūtra — which descends from the Mahāprajñāpāramitā literature traditionally connected with Nāgārjuna’s Dà zhìdù lùn — was a particularly congenial text for this Tiāntái-Madhyamaka self-positioning.
