Phitsanulok Dhammakaya inscription

The Phitsanulok Dhammakāya inscription (Thai: จารึกธรรมกาย พิษณุโลก) is a 16th-century stone inscription found in the stūpa (chedi) of Wat Tham Suea (also reported as Wat Suea) in Phitsanulok, northern Thailand. The inscription contains an early extant version of a text known as the Dhammakāya or Dhammakāya Gāthā — a post-canonical devotional/ritual recitation associated with pre-modern Thai-Khmer Buddhist liturgical practice — and is dated to the mid-16th century (often cited as 1548/1549 CE).^[1][2]

The inscription was recorded and published in the mid-20th century as part of the Thai epigraphic corpus and was assigned identification number 54 in the official Corpus of Thai Inscriptions. The dating formula on the slab corresponds to a Mahasakkarāja year and is commonly rendered as Friday, first day of the third waxing moon, 1470 Mahasakkarāja — equivalent to 2092 BE, which scholars equate with 1548–1549 CE depending on calendrical conversion conventions.^[2][1]

The slab was originally found sealed within the reliquary chamber at the top of the stūpa at Wat Tham Suea (sometimes transliterated as Wat Suea or Wat Khao) together with other gold-plated manuscripts and relic material; archival reports identify the scribe as a monk recorded by name in the inscription (Maḥāthera Śribaṅśa) and the donor or patron as an individual styled Mahā Brahmakumāra supported by a group of donors.^[3]

The inscription preserves an early form of the Dhammakāya recitation (often called the Dhammakāya Gāthā), a Pāli-based devotional/ritual text used in certain Thai and Lao liturgical contexts related to consecration formulas and meditation/abhiseka rites. Scholarly work has produced annotated transcriptions and translations of the inscriptional text, situating it alongside other manuscript witnesses from the Lan Na and Khmer cultural spheres.^[1][4]

Scholars note that the inscriptional Dhammakāya text is a post-canonical composition — i.e., it does not form part of the Pāli Canon (Tipiṭaka) itself but rather a later ritual-text tradition that was important in pre-modern Southeast Asian Buddhisms for Buddha-image consecration (buddhābhiseka), meditative schemas (kammatthāna), and other "boran" (ancient) practices.^[1]

The Phitsanulok inscription is widely regarded as one of the earliest objectively datable witnesses for the circulation of Dhammakāya material in the Thai-Khmer cultural sphere and therefore of considerable importance for historians studying the development and dating of pre-modern Theravāda ritual and meditative traditions in mainland Southeast Asia.^[1][5]

The inscription provides evidence for (1) the use of Dhammakāya verses in consecratory contexts, (2) the role of monastic scribes in producing ritual texts for reliquaries, and (3) cross-regional textual transmission (Lan Na, Siam, Khmer) of ritual verses across the early modern period.^[1]

The slab was catalogued in the national corpus of inscriptions and has been discussed in epigraphic and religious studies literature. Reports indicate the slab was originally sealed inside the stūpa reliquary; extant publication history is dominated by scholarly transcription, translation, and commentary rather than broad museum display publications.^[2][1]
