If so, why don’t those of you that have mastered this, have an out of body experience and go back to the future and get the Powerball Jackpot numbers??!!
If you can go into the future, your welcome! You can thank me with $25,000,000 via PayPal! lol! 
Maybe because some other astral projection master will want those lottery money and prevent you from taking them?
Its more likely astral projection masters to be already aware of this and they have other methods of rewarding apart from money. Information in this case can be much more expensive than money, since money can be obtained really easy by the masters, and information cannot.
