Chaharshanbeh Soori celebration in pahlavi period

Before the start of the festival, people gather brushwood in an open, free exterior space. At sunset, after making one or more bonfires, they jump over the flames, singing sorxi-ye to az man, zardi-ye man az to, literally meaning “your ruddiness mine, my paleness yours”, or a local equivalent of it. This is considered a purificatory practice.
