How can you represent Karma for a tattoo?

I've been trying to figure out this very same problem. I saw an ambiagram that was really cool. Just type it in a google search for Karma Ambiagram. it'll bring up a page that is it written as an ambiagram (you can read it, then flip it upside down and it still says the same thing). and it as an Ambiagram Circle that is just awesome. But, as far as symbol, the only real symbol for Karma is the Wheel of karma, and it's really just not that Visually stimulating. there is also a Japanese kanji that means Karma, it's eye appealing, and it means karma. But, there arent' a lot of options as far as single symbols go. Good luck. I've been trying to figure out this very same problem. I saw an ambiagram that was really cool.
