A systematic survey of the Tibetan non-canonical literature dealing with Sanskrit grammar, partly consisting of translations of Indic works and partly of original Tibetan works. The book then goes on to address the influence of Indic models of linguistic description on Tibetan indigenous grammar. This particular assimilation of an Indic technical discipline into Tibetan scholarship is examined in detail, and it is shown that other segments of Indic Buddhism were sources of inspiration and derivation for the Tibetan grammarians as well.
