With gratitude I have received one koku of soybeans and respectfully made a report of this at the altar of the Lotus Sūtra. It is said that a drop of water thrown into an ocean will never be lost even when the three calamities strike and a single flower offered to the Heaven of Pure Inhabitants (Jōgo-ten) will not wither even in the “kalpa-fire” at the end of the world. Likewise, a grain of soybean offered to the Lotus Sūtra will become lotus flowers beautifying the entire Dharma-realm.
