Haha, thanks for your comment! Yes, @atmosblack mentioned this book as well in his comment. Thing is, I haven't even read it...;)

Many of these things I describe are insights I experienced myself without having read anything. Generally, there has been only one 'teacher' I ever resonated with, which was David Cowan from Bolder Colorado. I was in regular email contact with him, and he passed last year now surely enjoying himself elsewhere in the Universe :)

Thank you for your nice comment! :)
