Some of us might like to ask: “What on earth is a Sa-phud-bla-ma (“Sa-omitting-bla-ma”) or Sa-gcod-bla-ma (“Sa-excluding-bla-ma”)? Well, these are nicknames given by Tibetan grammarians to sDe-dge-bla-ma Nor-bu-bstan-’dzin, who has maintained that secondary postscripts (yang ’jug), are not attested in Thon-mi’s treatise but were created later at around the time of gTsang-nag-pa Rig-pa’i-seng-ge. Sa-phud-bla-ma was a contemporary of Mi-pham (1846–1912). For a discussion, see Tshe-tan-zhabs-drung, Thon mi’i zhal lung (pp. 95–104, 198–199).
