According to the sacred Hindu texts known as the Shastras, neglecting to perform the nitya karmas will lead to sin. Examples of nitya karmas include:
- Snana yatra - bathing
- Sanshyavandanam - religious rituals performed at the opening and close of the day
- Aupasanam - keeping the marital fire burning
- Agnihotram - heated milk offering
There are different nitya karmas necessary at different times of the day. Some nitya karmas only need to be performed by certain people; for example, those who are married or have undertaken particular religious initiations.
A subdivision of nitya karma is nai-nitya karma. These karmas are considered compulsory yet conditional, depending upon the individual's circumstances.
