What's the difference between Actual Grace and Karma?

I was thinking about donating to the [Best Podcast in the Universe](http://www.noagendashow.com/) but they always give out "Karma" for donors, and being a Catholic, I don't believe in Karma, but I do believe in Actual Grace and I do believe that Actual Grace is something God gives you to continue doing good things. Can it be in reward for doing good things and to perpetuate the doing of good? Are our good deeds tantamount to a prayer? **Note:** The *Catechism of the Catholic Church* says this about "actual grace": >Actual graces ... refer to God’s interventions, whether at the beginning of conversion or in the course of the work of sanctification. (paragraph 2000) --- Excellent answers are wholly Catholic, apostolic, etc... And should contain the word Distinguo or at the very least the phrase "It would seem that..." (meaning please don't disregard the premise offhandedly until you've defeated the premise with your artful and oh-so-scholastic rhetoric). They would also speak to a wholly superficial knowledge of Hinduism and Karma, which is all that I have; which I gleaned from playing Fallout and watching Dharma and Greg as an adolescent.
