Interpretation:
The Proof is the Kanrodai or Central Pillar. The Central Pillar is the proof of the beginning of human beings. This is the location where God placed the pure mind of God in both of the first parents of human beings. This is why knowing the Origin is very important. God created the human body to live the Joyous life; but unfortunately we have strayed away from this life because we have contaminated our once pure mind with dusts or evil thoughts. God wants us to return to the Original mind, so we can live the Joyous life, which was the intention of God.
