I found the most effective technique for ap. They say if you can keep your mind on one thing while drifting off to sleep you can ap. Only problem with this is your mind wanders or thoughts enter the mind a lot. You should check out the koan and duality techniques that are offered at mysticweb.org investigative course after you taken astral/self knowledge/journey to enlightment you can enrol in the investigative course. To make a short story short the koan technique is to give your mind a question or situation that it cannot answer and it will silence itself as a result duality is like substitute the opposite of any thought that enters the mind to neutralize it. If you want to learn what the techniques are in detail best to enrol in the course. I can't believe I was able to do it even my awareness was low ie I ap'd but I was drowsy cause I projected before I went to bed but somehow this silencing of thoughts technique is what did it the other techniques are like awareness think at one thing at a time can also help you ap as well. I did the koan I had a few thoughts I neutralized it with duality technique I had the falling sensation which meant my body was falling asleep then I knew at that point I can just walk out and I did. This I have to admit is my first conscious ap and I was lying down in bed, other ap techniques that helped before was going to sleep 4 1/2 hours wakeup wash face stay awake and aware drop back to sleep with awareness of one thing ie visualize an object or something then have it in the mind etc..
