Bānruò xīnjīng mìjiàn lüèzhù 般若心經祕鍵略註

Abridged Annotation on the Secret Key to the Heart Sūtra by 覺鑁 (記)

About the work

A one-juan late-Heian sub-commentary on 空海 Kūkai’s Bānruò xīnjīng mìjiàn (KR6c0199, T57n2203A, the Hannya shingyō hiken). Composed by 覺鑁 Kakuban (1095–1144), the principal late-Heian Shingon reformer. Signed under the modest title shāmén Juébàn jì 沙門覺鍐記 (“the monk Kakuban records”). It is a word-by-word annotation of Kūkai’s Hiken — taking each significant phrase or compound from Kūkai’s text in turn, glossing its meaning, citing parallel doctrinal references, and unpacking its Esoteric implications. The companion to KR6c0123 (Kakuban on the Rishukyō) and a key witness to the early-12th-century Shingon institutionalization of the Kūkai commentarial tradition. Preserved in Taishō Vol. 57, No. 2203B (compiled with the parent Hiken under the joint T2203 entry).

Abstract

The text is a phrase-by-phrase running annotation of Kūkai’s Hiken, organized as the parent text proceeds rather than under a separate doctrinal scheme. Each annotation-unit takes a particular phrase of Kūkai’s text as its lemma (set off in single-character markings in the Taishō layout) and supplies an exposition.

Sample of the opening expositions:

  • Mì-jiàn 祕鍵 (the title): three glosses — (1) both characters are agent of explanation; the phrase means “the key that draws out the Esoteric teaching and opens the Prajñā-sūtra’s store”; (2) mì = the parent sūtra; jiàn = the explanatory comparison; (3) mì runs through both sūtra and commentary, jiàn the same.
  • Wén-shū 文殊: the bodhisattva Mañjuśrī, “Wondrous Auspicious One,” “Wondrous Virtue,” or “Wondrous Sound” — the wisdom-virtue of all buddhas, the awakening-function of the three bodies. Justification for invoking him at the opening of a Prajñāpāramitā commentary: “Mañjuśrī is the principal of all Prajñāpāramitā stores.”
  • Lì-jiàn 利劍 (“sharp sword”): Mañjuśrī’s samaya-emblem held in his right hand; lì praises prajñā’s spiritual virtue, jiàn enacts wisdom’s marvelous essence.
  • Jué zhūxì 絶諸戲 (“cutting off the proliferations”): cuts arising, ceasing, eternal, non-eternal, going, coming, identical, different — i.e., the eight negations (bā bù 八不) of the Mādhyamika. Why does Kūkai say zhū (“the proliferations”) rather than bā (“the eight”)? Because zhū covers gross and subtle, root and branch, all delusional barriers — bā is the abbreviated number, zhū the comprehensive name.
  • Jué-mǔ 覺母 (“mother of awakening”): the Prajñā Bodhisattva herself, the three-time mother of awakening, the deep wisdom of Vairocana-Dharmakāya.
  • Fàn-wén 梵文 (“Sanskrit script”): the bookcase (梵篋) held in Mañjuśrī’s left hand, the samaya-emblem of Prajñā and additionally of Mañjuśrī himself. “Within this case is stored the immeasurable and boundless mantras, the Sanskrit script of innumerable kalpas.”

The methodology is systematic technical sub-commentary characteristic of the late-Heian Daigo-ji / Mount Kōya scholastic tradition. Every term is given (a) its etymology, (b) its Esoteric maṇḍala-deity referent, (c) its associated samaya-emblem, and (d) the relevant scriptural citations. The architecture is recursive: the work is essentially a doctrinal lexicon of Kūkai’s vocabulary, presented in the order in which the terms occur in the parent text.

Dating. Kakuban took monastic ordination at Mount Kōya in 1107 and died in 1144; the Hiken ryakuchū is one of his many doctrinal commentaries on the foundational Kūkai corpus. No more precise dating is securely established. The signature shāmén Juébàn jì (using the modest jì “records / annotates” rather than zhuàn “composes”) flags the work’s character as a school-internal annotation rather than an autonomous treatise.

Translations and research

  • Henny van der Veere, A Study into the Thought of Kōgyō Daishi Kakuban, Leiden: Hotei, 2000 — principal English monograph on Kakuban; treats his commentarial corpus.
  • Inaya Yūsen 稲谷裕宣, Kakuban no kenkyū 覺鑁の研究, Kōyasan: Kōyasan Daigaku, 1969 — principal Japanese monograph.
  • Japanese-language scholastic commentaries on the Hiken-tradition; Kakuban’s sub-commentary is regularly read together with the parent text.

Other points of interest

The text is a model early-12th-century Shingon school-commentary of the lemmatic-annotation form — the lüèzhù 略註 (“abridged annotation”) genre. The form has clear scholastic precedents in the Tang Buddhist exegetical tradition (e.g., 一行 Yīxíng’s annotations on the Mahāvairocanasūtra) but was institutionalized in the late-Heian Shingon school as the principal vehicle for transmitting the Kūkai textual heritage to the next generation of disciples. The compilation of T2203A (parent text) and T2203B (Kakuban’s annotation) into a single Taishō entry reflects the standard pedagogical pairing in the Shingon scholastic tradition: the Hiken is rarely read in pre-modern Japanese Shingon institutions without Kakuban’s Ryakuchū as the inseparable companion.
