I'd like to learn more about NLP too.
Those letters I think have to do with 'sensory modalities' ("Natural Brilliance" p.141). If I remember correctly, I think Brian used them to explain some of his experiences. Not sure anymore whether they had to do with NB or kundalini. Or both?
I hope you got some sleep, Ramon.
