I can't say that I have had any major sudden changes due to paradigm shifts, or enlightenments. Things that have changed or that have become more deeply understood, have all come slowly over time--I'm generally a very slow, steady moving person; the 'slowly but surely' type.
I did appreciate how the use of the term 'personal truth' could lend itself to being a truth that is taken to being so personally. That is one major thing that most surely goes along with epiphenomenalism, which although not generally related to the word epiphany, is from the same root. The 'how' of each individual's seeing is the key player I think.
Well, as for my changes, one may be that of coming to see the purpose in life as most observably and likely, being just that--to have and ensure life on each plane of life. (we all do it in one way or another, and have built in systems to protect ourselves and so on.) This has come over a number of years. I'll post more if I think of it.
