Karma is about shifting responsibility from heaven to yourself. In this, you become the very maker of your own destiny.  

Conscious action does not produce karma – instinctive reaction does.

Whatever you do, just check – is it all about you, or is it for the wellbeing of All. This settles any confusion about good and bad karma.  

If you become truly meditative, you will be beyond karma.

Karma means ultimate responsibility. You even take responsibility for your very Birth and Death.
