Thanks all, I've skimmed over Xanth's book once, will look again! I haven't gotten to the astral again since then, a mixture of mindset/disturbance, I can only practice on weekends when waking up, as I have never gotten sleep paralysis before, I find I go into a state of peacefulness, but never get to the stage where I'm ready to go, haven't heard any sounds like ringing yet. My mantra is usually clear, but I have to put in effort to maintain it as I fall asleep as the words turn into other rhyming words, and I'm just guessing what goes next.
