Purification as Shinto's Living Practice

The purification Izanagi performs, harae, did not stay confined to this one mythic episode. It became, and remains, one of the central ritual acts of Shinto practice, performed today at shrine entrances through hand and mouth rinsing, and in fuller form by priests using water, salt or a waved paper wand before festivals, before entering sacred precincts, and after events regarded as sources of pollution such as death or serious illness. The myth supplies the ritual with its founding logic rather than merely decorating it, since Izanagi's own washing establishes that contact with death defiles even a deity and that the remedy is not punishment or atonement but cleansing through water. That logic runs through the annual Oharae rites held at shrines nationwide each June and December, which use the same basic vocabulary of purification the Kojiki attributes to Izanagi at Tachibana. The birth of Amaterasu from this act also gives the imperial line, which traditional accounts trace to her, an origin bound up with purification rather than conquest or creation from nothing, a detail later Shinto thought returned to repeatedly when explaining why ritual purity carries the theological weight it does across so many otherwise unrelated observances.
