They say karma is like a ball bouncing off the wall. The heavier you throw it, it comes back twice. We are all part of one system, and people who do bad will have their karma's and so on with doing good things. So before you act, make sure to always remember these things:
"Karma isn't fate. Nor is it a punishment imposed on us by some external agent. We create our own karma. Karma is the result of the choices that we make every moment of every day."
TULKU THONDUP, Peaceful Death, Joyful Rebirth
"Never ever blame God for anything that happens to us. We will realise that we are responsible for all that happens to us. As we sow, so shall we reap. Rich or poor, saint or sinner, miser or philanthropist, learned or illiterate ... This is the Universal Law that applies to individuals, to whole communities, societies, nations and races. As we sow, so shall we reap."
