I'm trying to find a digital text for the Ratnadārikāpariprcchā sutra, which Takasaki identifies as the source for the 64 buddha qualities in chapter III of the Ratnagotravibhaga; it is Taisho 399 (sometimes given as 400) and is chapter 3 of the mahasamnipata sutra.
The Tibetan title appears to be "bu mo rin chen gyis zhus pa'i mdo". I can't find it under this or the sanskrit in AIBS or THDL or any other catalog I can google up.
TBRC seems to have it and says "mdo sde spyi'i rnam bzhag Volume 1 Pages 248 - 250", but I don't know what this means.
Can anyone point me towards a digital or Wylie version of this sutra? I've hit the ceiling of my tiny Kangyur navigation skills.
