Dear Dominik, Dear Colleagues,
Attached (I hope) the very file you mentioned: a 'tapuscrit' of Jean Filliozat, signed by Arion Roșu as unpublished (back then).
Some related material is extant in Arion Roșu's archives in Paris and in Bucharest (which I just checked). It goes without saying, Arion Roșu meticulously abstracted his revered master's teaching courses at the College de France, his hundreds of handwritten pages during the 1970s being a better proof of Filliozat's mastery of all things Indological than his shorter articles from the Annuaire (freely available online). Please add the ZDMG reference follows the discussion from his 1978 book (s.v. visha / psychotropes). Hope it helps, even if the quality of my photo is rather poor.
with all best wishes,
Eugen
