Alex I hate to ask, or even seem to rain on your parade, but....
while the topic may be interesting, what purpose does it serve you?
Have you attained or experienced 8th jhaha, nirodhasampatti....?http://www.palikanon.com/english/wtb/n_ ... apatti.htm
How useful is this, and what need does it fulfil to know these things now?
Can anyone here truthfully answer your questions to complete satisfaction?
I know, in my profound ignorance that i have tried - and failed.
Others, far more learned than i have also tried....
why is this of use to you now?
