It seems you may mean samiti in Jain Dharma.

Samiti means careful, mindful conduct in daily actions so that ahimsa is not broken even unintentionally. In Jainism, the main 5 samitis are:

1. Irya samiti – careful walking
2. Bhasha samiti – careful speech
3. Eshana samiti – careful acceptance of food
4. Adana-niksepa samiti – careful handling of things
5. Utsarga samiti – careful disposal of waste/excreta ( jainknowledge.com)

These are especially important for Jain ascetics and are part of the discipline that helps stop karmic influx. ( jainknowledge.com)

If you meant a different term by “pravar samiti,” it is not a commonly used standard Jain term.
