Nusa is also used in different ways. In the present day, it is shaken noisily as if to purify dust, but in ancient ceremonies such as at Kasuga Taisha, it is stroked. The same is true at Ise Shrine, where noisy purification is forbidden. Today, Nusa is used by waving it left, right, and left toward the person or object to be purified, which is believed to transfer impurities to the Nusa. In the past, it was left, right, and center.
