Do you believe in Karma?
I do. Very very strongly... even tho I'm not a follower of religion.
Karma is the action which establishes cause and effect.
If you do something bad. Something bad will befall you.
If you do something good. Good things will befall you.
I behave myself purely because I don't want bad things to happen to me. I try and do at least ONE good thing a day.
I know people who did bad things. They got karma. Big Time.
