The following is NOT printed on this sticker:
Many Western cultures have notions similar to karma, as demonstrated in the phrase what goes around comes around. Christian expressions similar to karma include reap what one sows (Galatians 6:7), violence begets violence and live by the sword, die by the sword.
In Hinduism, God plays a role and is seen as a dispenser of its version of karma. The non-interventionist view is that of Jainism and Buddhism, the latter originally a non-theist religion. Generally, Western popular culture portrays karma as more of a supranatural mystical force than a perspective on causality. This is more similar to Hinduism's concept of karma than Buddhism's.
All of these interpretations leave plenty of room for the question: WTF?
