This volume contains groundbreaking research from scholars specializing in the Buddhist literature preserved in Tibetan translation in the Bka’ ’gyur and Bstan ’gyur collections. The authors of these chapters examine Tibetan strategies for organizing Vinaya literature, polemical debates and issues of apocrypha in the dhāraṇī and sutra literature, the formulation of the Phug brag compendium of dhāraṇīs, the transmission of tantra collections in the Mustang Bka’ ’gyurs, the kriyātantra tradition of the Goddess Mārīcī, linguistic analyses of the mahāsiddha Saraha’s abecedarian poetry, and Buddhaśrījñāna’s work the Jinamārgāvatāra as a window onto the lived tradition of Buddhist authors.
