Thanks very much for that information. I understand the distinction now. As the deep meditation and mantra are working it seemed sensible to carry on with something that is achieving results and it's good to know that the alternative self enquiry is weel known and understood.
In many ways 'self enquiry' seems to parallel my NLP training. It was a big 'eye opener' to discover the possibility of living in 'The Matrix'and knowing that can help with self discovery (infacr it was my first major step in that direction) and obviously in helping people overcome personal hurdles and achieve goals. The thing is, though you understand something new using NLP, it really only sticks in a more external way.
