Oh I've seen Wild Wild Country, that made sense to me and there's a logical thread to follow. Osho was also (for some time) a legitimately intelligent and charismatic leader/writer/philosopher able to rally smart people.

The story here on Wikipedia paints a picture of a destitute super-fringe cult that disappears for 20 years and then emerges with some level of tech wizardry and no mention of anyone that was responsible for that. There is an HBO docuseries.
