Interpretation:
God describing the condition of the world before the beginning of human beings I believe through evolution, it has taken millions of years to attain the human body that we have today. But it is God that began this process in the muddy oceans. I also believe that we have not reached our potential that God had envisioned in the beginning. As our minds become more spirited or pure, our bodies will eventually reach their potential that God had envisioned in the beginning. Remember, human beings were made to live the Joyous life. In the Ofudesaki, God predicts a life without death, illness, aging, etc.
