Mircea Eliade's book Yoga: Immortality and Freedom has deservedly become a classic, and has reached, as he intended, a far wider audience than the narrow circle of Indologists. The book's popularity may justify the following remarks. It was originally published in French in 1936, then in an enlarged French version in 1954, and in English translation in 1958. There has thus been ample opportunity for revision, and indeed in the second English edition (1969), which we are taking as our text, Eliade notes (p. xi) that he has made ‘numerous minor corrections’. However, the accuracy of his observations on early Buddhism still leaves much to be desired. Let us try to set the record straight.
