7. Understand, the fly, upon reaching maturity, lays her eggs wherever it sits down, and then it forgets about them. Millions are scattered by the wind into all regions of the earth, millions go into the water, yes, you probably cannot think of anything on earth, which remains free from its eggs. Since there is, so to speak, nothing so holy on which it might not land or which it may not sniff, therefore, other than glowing coals and a blazing fire, there is almost nothing, which the fly might not smear with its eggs.
