The quest for material gain, fueled by craving leads to suffering, or as the Buddha says: “You will be burned by them.” In the case of the Parable of the Burning house the children inside were so busy engrossed in their games, in their play, in their pursuit of happiness that they failed to notice the house was on fire and they were in great danger. If we approach our Buddhist practice as a way to gain benefit and not as a way to become enlightened then we will continue the cycles of suffering, of getting burned. Instead we should approach Buddhism as a way to become enlightened.
