An earlier article (Apple, J Indian Philos 41(3): 263–329, 2013) identified for the first time a brief Tibetan commentary to Atiśa Dīpaṃkaraśrījñāna’s (982–1054 c.e.) well-known “Entry to the Two Realities” (Satyadvayāvatāra) and provided an annotated translation of the work. This article provides an annotated diplomatic edition of the Tibetan commentary. The manuscript of the commentary is a facsimile reprint located in the recently published “Collected Works of the Bka’-gdams-pas” (bka’ gdams gsung ’bum). The early Tibetan commentary to Atiśa’s Satyadvayāvatāra provides direct textual evidence of the beginnings of scholasticism in Tibet and offers an early perspective on the formative developments in the intellectual history of Tibetan Madhyamaka.
