Great discussions, everyone!
E2B I enjoyed your posts and yes, I agree that neural-re-wiring is essential. Even after realizing your true nature, the old habits are there. This old conditioning needs to be replaced by the new world-view and this takes time (and effort). Brick by brick, layer by layer, the new neural pathways replace the old ones. Until the new world-view (of one as whole, complete and limitless) is the default one.
Even then, old ways of thinking will come up. But the default world-view will help neutralize them sooner. For example, just today, I had a strange day where I was plagued by mental tiredness/sluggishness (the blues?)--very unusual for me. But I was able to observe exactly what was happening. In vedantic terms--my tamoguna (fearful, lazy, avoidance) was dominant--and it was stirring up all sorts of unhealthy thoughts, emotions, patterns. I knew I needed to balance it out to get back to a sattvic (calm, positive) state of mind. Because I was aware, the whole process took about a day and now I feel balanced again. And that is simply because the new way of thinking is dominant now. And I expect that when this negativity happens again (and it's guaranteed to do so), then hopefully it will be an even shorter time to regain peace of mind. And that is how neuroplasticity works its magic
--the new signals replace the old ones, slowly but steadily.
Finally, I wanted to add (to the discussion that this forum is slow these days). I think of the forum as a reflecting the state of mind of the participants. From this fine thread, it is clear that many of us have found inner peace and the calm, quiet, confidence of this forum reflects that. But we are old friends here and always available to support one another should the need arise.
