जानता तु कृतं॑ पापं गुरु सर्व भवत्युत । अज्ञानात् स्वल्पको दोष: प्रायश्षित्तं विधीयते,जान-बूझकर किया हुआ सारा पाप भारी होता है और अनजानमें वैसा पाप बन जानेपर कम दोष लगता है। इस प्रकार भारी और हलके पापके अनुसार ही उसके प्रायश्चित्तका विधान है
jānatā tu kṛtaṃ pāpaṃ guru sarvaṃ bhavaty uta | ajñānāt svalpako doṣaḥ prāyaścittaṃ vidhīyate ||
Vyāsa said: A sin committed knowingly becomes wholly grave. But when a fault arises from ignorance, the blame is comparatively slight; therefore, expiation is prescribed in accordance with the heaviness or lightness of the wrongdoing.
व्यास उवाच
Moral weight depends strongly on intention and awareness: deliberate wrongdoing is treated as a grave sin, while faults arising from ignorance carry lesser culpability; accordingly, expiations (prāyaścitta) are graded to match the severity.
In the didactic discourse of the Śānti Parva, Vyāsa states a principle for ethical and legal-religious judgment: how to assess wrongdoing and determine appropriate atonement based on whether the act was done knowingly or out of ignorance.
