Firewns, thank you for participate in this discussion :)
I would like to point out that we do not have to “stay” in the words, we have to go deeper into the meaning of what the author mean to be with those word.
“egolessness”, “not-self”, “non-self”, etc… If we carefully examine what every author want to explain with those words they all mean the same, the ausence of a permanent sustance that keep intact whithin time and space.
With every author I refer to the ones that we are mentioning, Theravada tradition ones.
