First Published in 2000. The analysis of the Tibetan Bkah-hgyur by Alexander Csoma de Koros, struck its readers with the wonderful patience and perseverance of this extraordinary scholar. Csoma's premature death, prevented him examining as fully as we could have desired the Tibetan Bstan-hgyur, to elucidate the difficulties which so frequently beset the canonical works in the Bkah-hgyur. Throughout this volume no attempt has been made to criticise the texts which have been studied; they are only intended as materials for those who hereafter may undertake to write a history of the Buddha.
