Kamidana often enshrine the kami of a nearby public shrine as well as a tutelary kami associated with the house's occupants or their profession. They can be decorated with miniature "torii" and "shimenawa" and include amulets obtained from public shrines. They often contain a stand on which to place offerings; daily offerings of rice, salt, and water are placed there, with sake and other items also offered on special days. Prior to giving these offerings, practitioners often bathe, rinse their mouth, or wash their hands as a form of purification.
