The fire of hell in this world is hotter than that of the hell in the world-beyond. There is no fire equal to anger, lust or greed and ignorance. According to the Buddha, we are burning from eleven kinds of physical pain and mental agony: lust, hatred, illusion sickness, decay, death, worry, lamentation, pain(physical and mental), melancholy and grief. People can burn the entire world with some of these fires of mental discord.
