Amé Zhab writes that Ngorchen Kunga Zangpo personally examined three Sanskrit manuscripts of the sūtra, all of which were the “three oṁ” version,¹⁷ implying that there were no Sanskrit texts attesting to the “two oṁ” version. While there is little doubt that the “three oṁ” version of the text is indeed authentic to its source, Ngorchen’s claim that it is the only authentic version is explicitly refuted and dismissed by Tāranātha, who in his commentary says there were many Sanskrit manuscripts of both versions,¹⁸ and relates in his autobiography how, on a visit to Narthang, he was himself shown several Sanskrit manuscripts of the sūtra, of which one was clearly the “two oṁ” version.¹⁹
