Prāyaścitta

Prāyaścitta is the Sanskrit word which means "atonement, penance, expiation". It refers to one of the corrective measures in dharmaśāstra as an alternative to incarceration or other forms of danda (punishment) when someone is convicted of certain categories of crimes. The word is also used in Hindu texts to refer to actions to expiate one's errors or sins, such as adultery by a married person.

Those texts that discuss Prāyaścitta, states Robert Lingat, debate the intent and thought behind the improper act, and consider penance appropriate when the "effect" had to be balanced, but "cause" was unclear. The roots of this theory are found in the Brahmana layer of text in the Samaveda.
