Talk:Osho Timeline 1974
As mentioned in the article page, some uncertainty exists about when Chuang Tzu Auditorium became operational for Osho's discourses. As of this writing, no 100% reliable source -- ha ha! -- has been found for this information. Anecdotal sources suggest different things, and the announcements (of dates and venues) at the beginnings of discourse tapes have been expunged by Pune authorities, citing (as they do) Osho's guidance.
The CD-ROM does state venues but we have to note that it has the very first Pune One discourses in both English and Hindi in Buddha Hall, though neither it nor even Chuang Tzu had been built, so the CD-ROM may have reliability issues as well.
A more in-depth exploration of this theme can be found at the page on these venues.
