karma... do to others as you'd have them do to you.... do good out fo the kindness of your heart and you will be rewarded, do bad, and you'll face punishment 3x worse.

because it ust makes sense to me... and i've tested it over and over and it's yet to fail me... also it doesn't require some dedication or going ot church or any of that crap... the only stipulation involved is for you to live your life as a good person...
