The ritual known as the Procession of Unforgotten Souls occurs for several weeks, at night, prior to autumn feast. The faithful beseech Pharasma not to take them yet, and stand in silence. They then enter a fountain (although river, lake, or other body of water is equally common) carrying candles. When the priests emerge, the candles miraculously relight and the thin garments worn by the clerics become transparent after being saturated in the water. The festival colours beneath the garments are then clearly visible.[3] Although the procession is typically silent, it has become something of a tradition for the celebration to coincide with the migration of local birdlife, creating melodic birdsong that seems to accompany the celebration.
