The Book of Secrets
This URL is a legacy alias many old links still use. The maintained page with catalog links, edition notes, and context lives under Osho’s words—same title, fuller frame.
The book is a line-by-line style commentary on the Vigyan Bhairav Tantra: 112 meditation experiments framed as a dialogue between Shiva and Devi. Some techniques use sound, some stillness, some everyday acts. It is long; readers often work one chapter at a time rather than sprinting cover to cover.
