There’s a connection in the brain between being physically clean and feeling morally cleansed
Many religions involve washing, from Muslim prayer rituals to Christian baptisms. This weekend, in the period between last week’s Jewish new year and the holy day of Yom Kippur on Wednesday, Jews around the world are reflecting upon the sins of the past year and casting them off into water.
