To expiate the sin of Brahmahatya, Bhairava had to perform the vow of a Kapali: wandering the world as a Bhikshatana with the skull of the slain as his begging bowl.

Bhairava's sin was finally expiated when he reached the holy city of Varanasi, where a temple dedicated to him still exists.

[5] In regional tradition, Shiva as Bhairava is considered to have been entrusted with the task of maintaining law and discipline amongst Hindus, as pertaining to their salvation in the city of Varanasi, where the last rites of Hindus are performed in the holy river Ganges, with accountability of their sins and good deeds.

After taking a bath in the morning, devotees, especially Shiva-worshipping Shaivas offer libations and oblations to their dead ancestors.

On this day, an image of Kala-Bhairava is made in gold or silver and immersed in a brass metal pot filled with water and worshipped with all scriptural prayers, as is done to Shiva.
