Welcome Thrifty! I'm an Eckhart Tolle lover too! I have both The Power of Now and A New Earth...but have only managed to read a portion of the way into both due to time constraints, but with my upcoming ELEVEN DAYS off (kinda excited) I'll be able to continue reading. Where did you find the addiction info that you referenced above? I only found one small paragraph once about addiction and there are a lot of similarities in the split thinking he talks about and in AVRT. Especially in the form of watching your thoughts...not judging them but just being conscious of them.
But anyway, thanks for posting and welcome to the thread.
