Missing folios anyone?
The first one (verso of the title page) was already identified by prof. Harunaga Isaacson (sincere thanks!) as the starting page of Mahāmati's Tattvaviśadā Pañjikā to the Ḍākinīvajrapañjara.
A second runaway train is from the commentary to the seventh chapter of the Buddhakapāla by Abhayākaragupta and in all probability formerly part of NAK 5/21 = NGMPP A 48/2 as there is a lacuna here of several folios. This passage corresponds to ff. 44a4-46b4 of the Calcutta manuscript and contains four nice apabhraṃśa songs to awaken the Heruka.
The third one is a bit more puzzling. The text is from the Laghutantraṭīkā ch. 9., corresponding to Cicuzza 2001:98.4-100.29. and his folio 17a-17ab from Kaiser 225 = NGMPP C 25/6. It escaped my attention if indeed Cicuzza has a note on this. Is it possible that he took it over from the Catuṣpīṭhanibandha? Did he have a manuscript (the format is the same) with text starting and ending at the same place as the Nibandha stray folio? What is going on here? Does anyone have his email?
