The Sraddha Ritual : Purificatory Rites - Verse 74-75

One who has no faith in purificatory rites is born among Mlccchas. Those who do not perform Yajnas and sinners are born among the lower strata of animals. A man gets released from sins through purificatory rites and attains heaven. Devas indeed desire purity. This has been declared by Devas themselves.
