Izanaki lamented his dearest and made a travel to Yomi, the land of night, the land under ground, the world of the deads.
There he saw decayed figure of his wife, flew back, and divorced her. "My dear, I will kill each day one thousand of your peoples," she cursed him. "My dear, I will make them bear one thousand and five hundreds," he replyed. Hence, birth and death.
