Maybe someone can give me some pointers on ways to medtaite and things to focus on while meditating. I've read various how to meditate guides on this site and off-site. Even armed with that knowledge I don't seem to be able to acomplish it. I guess to be more accurate when I begin a meditative session I begin putting a goal in for astral projection into my mind. I just got done trying to do this. I put some headphones on and turned on a binarual beats clip I located on Youtube, and a blindfold to help block out distractions and focus my mind. After a while I'd feel a jerking sensation like a tug in a random part of my body, and it'd grab my attention bringing me back to being "awake". This continued for 45 minutes finally the clip ended and I immediatly woke up but it took a minute to actually get moving. I was laying down because sitting lotus style started to make my body ache. And while laying down I had to change resting position because after a while my body began to ache again.
I know this is a lot but I figured the more info the better less I leave something out. If anyone can give me some advice I'd appreicate it.
