Vikarma

Vikarma is a title given to people who are believed to be untouchable. The reason is because they are believed to have sinned in their past lives. They could not attend any rituals or holy ceremonies.

The Scrapping of the Vikarma Law
After Shiva came, he did not like the idea of Vikarmas. So, when Daksha asked him if he wanted to marry Sati, Shiva replied "Sure, your Highness. But the entire Vikarma law must be scrapped. No one will be a Vikara from now on!"
