I actually came to PON after finding the silence and I-am ness through a process of questioning beliefs. I was glad to find someone who could explain simply what was happening.

Tolle was great for me because he asks us to stay in this I-am'ness or Nowness and not just dispel it. And that has led to a huge "fundamental shift" as you say.

Just because some of these things have been known for thousands of years and have been talked of by Christians, Buddhists, Hindus etc, does not mean they are a set of beliefs (as some are suggesting).
