Anyway if you are stage 5 or 6 when you are young, then you have
to be stage 5 or 6 right now. And you have no doubt about dharma
and knows in real time, intuitively, not just conceptually, things
like:
# The arahat knows in real time and directly what is meant by
such phrases and concepts as:
1. "in the thinking is only the thought, in the seeing is only the
seen, etc."
2. intrinsic luminosity
3. the emptiness of phenomena
4. that Nibbana is found in Samsara
5. and a whole host of other poetic metaphors and attempts as
description.

If you say you are very sure you know all these in real time, then
I don't think you are being honest with yourself and us.
