I talk to my dad about this all the time...just read the instruction manual and try not to worry about it. The jacket of the cd is worth its weight in gold! This topic gets posted alot, in fact I've even asked what I'm doing right and wrong when it comes to this. Everytime the answer comes back...listen to what Paul has come up with. I get very connected with the universe when I listen to PL...but when it comes down to the rubber meeting the road so to speak its all science. Look into how much research goes into these, Paul and LS really does there homework!
Best of Luck
