Neti-Neti (नेति-नेति)

Neti-Neti literally means "not this, not this," and more loosely "neither this nor that." It is used widely and traditionally as the name for a quasi-analytical method of discarding psychic debris, a sort of "via negativa" tool of self-exploration, more particularly, disidentification. More about this can be found at Wikipedia. This page is about a four-volume series of books created from some of Osho's early discourses.

The four books are presented in different ways by different sources, and usually not all four together but grouped in varied ways. They are:

• Satya Ki Khoj (सत्य की खोज) (dated by different sources as Jan 16-19, 1970 and Feb 25-27, 1969, likely at a meditation camp. Since all sources indicate 5 discourses, the January dates are less likely. Another possibility is that SKK is the title of two different books, one associated with Neti-Neti and the other not.)
• Shunya Ki Naav (शून्य की नाव) (dated by only one source, May 2-5, 1968, 7 discourses)
• Sambhavnaon Ki Aahat (संभावनाओं की आहट) (undated, 7 discourses)
• Shunya Ke Paar (शुन्य के पार) (undated, 4 discourses)

The reason these four books are so grouped is not clear but the grouping does happen widely. Thematically, the first three are about meditation, sadhana and so on, the last is said to be a Q&A format. The time span is unknown. More info will be needed.
