| I could write a whole blog post on the problems I have with it, but it boils down to one fact: our mind, ego, thoughts and feelings are inseparable from each other.
Who said they were separate ?
I agree that sometimes Tolle does use terms which may not be real such as "pain body" ( I also did not like it when I first read Power of Now) but I understand that he creates these terms more to help understand something.
| he is imprecise with language
I don't think you can be precise in this particular case. When you speak of something which is actually the subject, and not an object, where there is no subject-object separation, then it is very difficult to be precise.
Let me give you an example from your own post:
| There is one consciousness, and my goal in meditation is to focus my consciousness on my consciousness
Who is this "my" who has a goal in meditation and even more importantly when you say "my consciousness" then whose consciousness is this you speak of. Are you some other entity who has a consciousness ?
Let me clarify that I am _not_ a Tolle follower, I follow self-enquiry, but I have found Tolle's PON to be a great book that I been able to appreciate _after_ having reached some measure of "presence".
