I am deeply shocked to learn about the early disappearance of Yves, this most sympathetic and remarkable personality whom I first got to know when he was scientific assistant at the Université de Lausanne during my stay there (as PhD student) in 1990-91.
Later on we met again in India when he had already come to Pune to help prepare "the first international conference on Bhartrhari" organised by Saroja Bhate and Johannes Bronkhorst. Apart from practical matters in connection with the conference he was much occupied with perfecting his Bibliography on Bhartrhari and tried to make full use of the occasion of being now in India and finding perhaps rare and unexpected references.
One place, he insisted, was particularly important to check out, and he wanted me to come with him on this mission: he wanted to know whether Rajneesh (who had died a few years earlier under the name Osho) had perhaps occasionally in one of his numerous books referred to Bhartrhari. After all, Rajneesh had always claimed to have had a good training in philosophy and his books and speeches were teeming with references to Jesus, Shankara, Mahatma Gandhi, Gorakhnath, Kabir, Gurdjeff and also Patanjali [but this must be not the grammarian but the one involved in yoga]. When we finally found a moment to go the Osho ashram in the Koregaon area of Pune we were well received in the ashram -- full of "western" followers -- but soon found out that even the most literary minded among Rajneesh' disciples could not confirm he had ever read a reference to Bhartrhari. We were ready to believe him on his word (rather than starting to sift through the pile of Rajneesh's books that had been made available) and politely declined the offer to see a filmed speech of Rajneesh on imminent nuclear disasters that would destroy the world. The end conclusion was that the Bibliography on Bhartrhari did not need to mention any book of Rajneesh (or Osho).
After the first version of 1993 Yves Ramseier produced an updated and much extended bibliography on Bhartrhari which was published in Bhartrhari: Language, Thought and Reality (ed. Mithilesh Chaturvedi), Delhi, 2009.
The Word Index to the Prasastapadabhasya (Delhi, 1994) already mentioned also contains an "edition" based on 12 existing editions of the Prasastapadabhasya.
