A wild concept about the Burning Candle!!

Lighten up a candle and the room glows! You could have a romantic dinner on one front; on the other, it might be used to lit a few houses where electricty has not been heard of! Have you ever thought of the burning candle - "It lights up darkness and at the same time sacrifices the wax".. For every goodness we see in this world, a price would have been paid, like they say - someone's loss would be another mans gain!
