Hi Adam. I have enjoyed parts of the book...
She explained a couple of things that have helped me...there were pics of her in the traditional postures for meditation and she described them. It helped because one of those two poses was the one I use and not many people in AYP do, so I didn't feel so different then, compared to everyone else---it is nothing more than the way you hold your hands while you meditate.
Another thing was her description of the locks to keep the spine very straight while meditating...and her comment that if you had a very erect spine, with alignment from the root to the crown, that you would have a deeper meditation. I've noticed that in my case, it is true. I've had a tendency to be slouchy when meditating and when I lock down, and straighten root, back, chin and up, I stay on mantra and have deeper, more profound meditations.
One thing is different for me than her experiences...she experiences the sound current while meditating, but I hear it prior to falling off to sleep....
I really appreciate the 'open', inclusionary, sharing learning that we have in AYP, so I probably won't pursue any mystery school. Right now, AYP is the core of my practice and other things are secondary. I'm deeper in my practice than I have been in a long time, adding more practices now without (knock wood) side-effects. I still read as much as I can in my limited down time from all other sources and take from them the gems I always find within, just as I've done with Earlyne's book. As Yogani says, the guru is within. Others I know say the master is within.. I'll finish her book and read others I happen upon because some of what she has said rings true for me...
light and love,
Kathy
