Interpretation:
We know that illness exist in the world, but God tells us that illness should be nonexistent in human beings. God gave the first parents of human beings the Original pure mind of God. This is a mind that will bring upon only joy. This is why God tells us that illness should be nonexistent. God wants us to return to this pure mind. This is a mind without regret (oshii), covetousness (hoshii), self-love (kawaii), greed ( yoku), and arrogance (koman). Illness comes from the mind (from Mikagura-uta song 10).
