In Japan, from ancient times, such items as sake, salt and rice were used to purify the land. Even Buddhism offers flowers and incense to purify the place and to entreat the protection of the Earth Buddha and the deities of heaven and earth.

Shakamuni Buddha taught his older brother, Makahandoku, once “when cleaning with these recite clean dust, remove filth.” This is not only to beautify our place, but he came to realize the fact that his soul was caused to shine by cleaning away his mind’s dust and filth. He came to believe that the dust and filth that was fixed to his mind was the mind of attachment that was too concerned about things, the mind of self-deprecation, as well as the greedy mind and the mind of ignorance.
