I think this has to do more with what door one comes in through to the dharma (dhamma) than anything else. I always heard the terms "ultimate reality" and "non-dual" used, so it is very natural for me to use these terms when referring to "no such thing as "me" and "mine". When somebody says there is "no such thing as "me" and "mine", then of course, this comes as a surprise to most people, who are likely to point to themselves and say, "well, here I am". So naturally the question arises, "if you claim there is "no such thing as "me" and "mine" then why is that? How can that be true? On what basis is this true?"
