Tibetan Buddhist canon

• 1. Royal Catalogues of the Eighth Century

  ›

  In 814 CE, a team of Indian and Tibetan scholars completed a bilingual glossary known as the Mahavyutpatti. This document standardized terminology for all future translations into the Tibetan language. King Trisong Detsen issued decrees requiring that existing translation works be catalogued and reviewed. He appointed Bande sKa-ba dpal-brtsegs to lead this massive literary project. The king also ordered the compilation of three separate catalogues from royal libraries in different palaces. One catalogue was created in the palace named pho-brang 'phang-thang ka-med kyi gtsug-lag-kang during the dog year of 818 CE. Another followed in the dragon year of 824 CE within the library called pho-brang stong-thang ldan-dkar. These early records listed specific numbers of verses and folios for each text. They included physical descriptions such as word counts and canto lengths. The ldan-dkar-ma catalogue contained 735 titles under 27 subject headings. A recently rediscovered manuscript of dkar-chag phang-thang-ma lists 961 titles across 34 subjects. These documents established the foundation for what would become the Kangyur and Tengyur collections.

• 2. The Two Pillars Of Translation

  ›

  The Tibetan Buddhist canon divides sacred texts into two broad categories known as bka'-'gyur and bstan-'gyur. The first category, Kangyur, consists of works said to be spoken directly by the Buddha himself. All texts in this section presumably have a Sanskrit original, though some were translated from Pali or Chinese sources. The second category, Tengyur, contains commentaries and treatises written by great masters on the Buddha's recorded teachings. This section holds 3626 texts spread across 224 volumes. Modern editions of the Kangyur contain approximately 1,115 texts covering 65,420 folios. The Tengyur portion uses 127,000 folios to house its vast collection of philosophical works. Together these two sections comprise 4,502 texts containing roughly 73 million words. Editors take responsibility for removing texts they consider spurious or adding new translations. Currently about 12 different versions of the Kangyur exist in print or manuscript form. Each editor makes independent decisions regarding which texts belong in their specific edition.

• 3. Woodcut Editions And Manuscript Lineages

  ›

  Printing technology transformed the preservation of these sacred texts during the early modern period. The Yongle Kanjur appeared in 1410 but is largely lost today. A Wanli Kanjur was produced in 1606 with only a Berlin manuscript copy surviving from 1680. The Lithang Kanjur ran from 1608 to 1621 while the Kangxi Kanjur spanned 1684 to 1692. The Cone Kanjur took ten years to complete between 1721 and 1731. The Narthang edition emerged in 1730 followed by the Derge Kanjur in 1733. These woodcut editions often contained contamination from other textual lineages like Them-spangs-ma. Manuscript traditions developed separately from printed versions. The Shel-dkar manuscript exists via a London copy dated 1712. The Tokyo Ms Kanjur was created between 1858 and 1878. The sTog Palace Kanjur manuscript dates from approximately 1700 to 1750. Some local versions include the Bathang Kangyur manuscript and the Mustang Kangyur manuscript. The Phug-drak Kangyur manuscript covers the years 1696 to 1706. Tabo contains individual text fragments rather than a complete collection. Scholars Helmut Eimer and Paul Harrison have researched the stemma of these Kangyur editions extensively.

• 4. Hierarchical Tantra Classifications

  ›

  The Nyingma school divides tantric texts into three outer tantras known as Kriyayoga, Charyayoga, and Yogatantra. Three inner tantras correspond to the Anuttarayogatantra category including Mahayoga, Anuyoga, and Atiyoga. Atiyoga further splits into Mental Semde, Spatial Longdé, and Esoteric Instructional Mengagde classes. New Translation schools such as Gelug, Sakya, and Kagyu use four hierarchical categories instead. These include Kriyayoga, Charyayoga, Yogatantra, and Anuttarayogatantra. The final category breaks down into mother, father, and non-dual tantras. Mother Tantras correspond to what commentators termed ma rgyud in earlier schemes. Father Tantras include works like the Guhyasamāja placed in the ultimate class of Unexcelled Yoga tanras. Non-dual Tantra or Advaya Class features texts such as Manjushri-nama-samgiti and Kalachakra Laghutantra. The distinction between sutra and tantra is not rigid in some editions. Certain versions place the Heart Sutra within the tantra section alongside Pali Canon texts. This flexibility allows for cross-referencing between different Buddhist vehicles.

• 5. Indian Masters And Philosophical Foundations

  ›

  The Tengyur contains commentaries composed by Indian authors who shaped Tibetan philosophical thought. Asanga founded the Yogacara philosophical school while Nagarjuna established Madhyamaka philosophy. Aryadeva continued Nagarjuna's Madhyamaka tradition as his foremost disciple. Dharmakirti authored the Seven Treatises and debated Hindu scholar Adi Shankara. Dignāga was a famed logician whose work influenced later scholars. Vasubandhu served as Asanga's brother and contributed significantly to Abhidharma studies. Gunaprabha taught Vinayasutra as the foremost student of Vasubandhu. Sakyaprabha became a prominent exponent of Vinaya law. Atiśa held lojong teachings that influenced meditation practices across Tibet. Bhāviveka exposed Svātantrika interpretations of Madhyamaka philosophy early on. Buddhapālita developed Prasañgika interpretations during the same period. Candrakīrti stands as the greatest exponent of Prasañgika interpretation. Haribhadra commented on Asanga's Ornament of Clear Realization. Kamalaśīla wrote important texts on meditation in the 8th century. Śāntarakshita abboted Nalanda and helped Padmasambhava establish Buddhism in Tibet. Shantideva composed the Bodhisattvacaryāvatāra in the 8th century.

• 6. Five Topics Of Monastic Study

  ›

  All four schools of Tibetan Buddhism follow a similar curriculum using Indian root texts and commentaries. The exoteric study organizes into Five Topics with primary source texts for each area. Abhidharma relies on Asanga's Abhidharma-samuccaya and Vasubandhu's Abhidharma-kośa. Prajnaparamita centers on Abhisamayalankara and Shantideva's Bodhisattvacaryāvatāra. Madhyamaka studies Nagarjuna's Mūlamadhyamakakārikā alongside Four Hundred Verses by Aryadeva. Candrakīrti's Madhyamakāvatāra and Śāntarakshita's Madhyamākalañkāra also appear here. Pramana focuses on Dharmakirti's Pramānavarttika and Dignāga's Pramāna-samuccaya. Vinaya examines Gunaprabha's Vinayamula Sutra plus five treatises attributed to Maitreya. These Five Treatises of Maitreya comprise the heart of Shentong-Madhyamaka thought. They include Abhisamayalankara, Mahayanasutralankara, Ratnagotravibhāga, Dharmadharmatavibhanga, and Madhyantavibhanga. Some scholars believe Maitreya was a historical person who taught Asanga directly. Others view him as the future Buddha residing in Tushita-Heaven. A commentary called Clarifying the Meaning by Haribhadra often accompanies these texts. The Rimé movement brought together Kagyupas and Nyingmapas using many shared commentaries since the 19th century.
