The function of fire is to burn and give light. The function of water is to wash away filth. The winds blow away dust and breathe life into plants, animals, and human beings.

They are the cluster of blessings brought by the Bodhisattvas of the Earth, disciples of the Buddha in his true identity. -Nichiren
