Get a small candle (ideally a tea lite) and a holder for it. With a toothpick, engrave the words 'heal', 'love', and 'peace' in to the wax. Light the candle, say a little prayer of your choosing for the world, and send out some good energy. Let the candle burn out. If we all do this every night for a week, we will not only send out love and peace to the world, but feel more at peace with ourselves.
if you want good karma, teach a child to read or something like that. besides, i'm not allowed to play with matches
well, you can always volunteer... but there's nothing wrong with sending out a little love in to the world... if you can't play with matches, meditate infront of a lightbulb, what can I say...
