My impression is that it's U Pandita's own informal terminology, not specifically from suttas or commentaries. That particular translation may possibly have emerged out of discussions about the talks at the 1984 IMS retreat that the the book is created from. It might be better to focus on the definitions and discussion that he gives rather than the terminology. It seems to be largely an alternative description of the progress of insight, but emphasising the factors normally associated with the progression through jhanas, such as rapture, happiness, and equanimity.SarathW wrote:Can I safely say that there is no word as such "Vipassana Jhana" in Sutta?
The terminology might be a stretch. However, suttas such as the one I quoted, and of course the commentaries, do discuss the development of samadhi by watching arising and passing away of phenomena.
