In Jain Dharma, pravrajya means renunciation or acceptance of monkhood/nunhood — the act of leaving गृहस्थ life and entering the path of sanyam (discipline), tyag (detachment), and moksha-marg.

In simple words:

• Leaving worldly attachments
• Taking vow of celibacy and non-possessiveness
• Starting the life of a Jain sadhu or sadhvi

If you mean “pravijya” or another specific Jain term, the spelling may be different.
