injure Brahmins. Literature Pitrs have been featured in Hinduism since the Rigveda, with hymns invoking Agni to decide which offerings should go to the devas, and which to one's pitrs. In this text, the Pitrloka and Devaloka are regarded to be indistinct. They are regarded to be distinct in the Atharvaveda, and in the Brahmanas, Devaloka becomes preferable to attain to the Pitroka. The Manusmriti states that a son born of the Brahma marriage absolves the sins of ten pitrs on the ascending side, and ten on the descending side of his family, as well as himself as the twenty-first.

He states that performing the Shraddha ritual on each successive day of the lunar fortnight, one reaps merits, such as acquiring beautiful spouses and successful children on the first day, daughters on the second day, steeds on the third day, and so on.
