Testament of Ba

The Testament of Ba (Tibetan དབའ་བཞེད or སྦ་བཞེད; Wylie transliteration: dba' bzhed or sba bzhed) is an account written in Old Tibetan of the establishment of Buddhism in Tibet and the foundation of the Samye Monastery during the reign of King Trisong Detsen (r. 755–797/804), reputedly as recorded by Ba Salnang (Tibetan དབའ་གསལ་སྣང or སྦ་གསལ་སྣང; Wylie transliteration: dba' gsal snang or sba gsal snang), a member of the king's court. The earliest known versions of the text are two manuscript fragments dating to the 9th or 10th centuries that are held at the British Library.

The Testament of Ba was transmitted in manuscript form over many centuries, and so there are many different recensions of the text, but not one single, canonical printed version. Two early versions of the text have been identified by scholars:

The Testament of Ba is also widely quoted in later Tibetan historigraphical works, for example the Scholar's Feast (mkhas pa'i dga' ston). The author of the Scholar's Feast calls the Testament the Rba bzhed (with an 'r' prefix to the Ba clan name), and refers to 'genuine', 'impure', 'large' and 'medium' versions of the text.

A later, expanded version of the Testament of Ba, titled Sba bzhed zhabs brtags pa (Supplemented Testament of Ba), was produced during the mid 14th century. A manuscript copy of this text was published with a summary in French by Rolf Stein in 1961.

Up until 2009 it was thought that the Testament of Ba dated back to no earlier than the 11th or 12th century, and therefore its composition may not have been contemporaneous with the late 8th century events that it recorded. However, in 2009 Sam van Schaik of the British Library realised that two Tibetan manuscript fragments catalogued amongst the Chinese manuscripts of the Stein collection (and consequently previously overlooked by Tibetan scholars) preserved a section of the Testament of Ba relating to the arrival of the Indian monk Śāntarakṣita, abbot of Nalanda University, to Lhasa:
