Niyamavidhi literally means ‘restrictive injunction’.

According to the Purvamimānsā Darśana, the fifth in the series of Saḍdarśanas or Six Systems of Philosophy, the Vedas are full of vidhis[1] and niṣedhas.[2] One of the various methods of classification of these vidhis is into three groups:

  1. Apurvavidhi - injunction of something quite new
  2. Niyamavidhi - restrictive injunction
  3. Parisañkhyāvidhi - precluding one by injunction when two alternatives are possible

For preparing the puroḍāśa,[3] pounded rice is needed. Though un-husked rice can be de-husked by hand using the fingers or by pounding with a pestle, the Śruti restricts it to the second method as a rule. The sentence ‘vrīhīn avahanti’[4] is the example for a niyamavidhi.


  1. Vidhis means injunctions.
  2. Niṣedhas means prohibitions.
  3. Puroḍāśa means rice-cake.
  4. It means ‘He pounds the rice’.
