One of the most profound things about these insight stages is that they are strangely predictable regardless of the practitioner or the insight tradition. Texts that are 2,000 years old describe the stages just the way people go through them today, though there will be some individual variation with respect to the individual specifics today as then. The Christian maps, the Sufi maps, the Buddhist maps of the Tibetans and the Theravada, the maps of the Kabbalists, and many non-Buddhist traditions of India are all remarkably consistent in their fundamentals.
