Shloka 20
Prāyaścitta-vidhāna: Tapas, Dāna, Vrata, and Proportional Expiation (प्रायश्चित्तविधानम्)
दश वा वेदशास्त्रज्ञास्त्रयो वा धर्मपाठका: । यद् ब्रूयु: कार्य उत्पन्ने स धर्मो धर्मसंशये
daśa vā vedaśāstrajñās trayo vā dharmapāṭhakāḥ | yad brūyuḥ kārya utpanne sa dharmo dharmasaṃśaye ||
毗耶娑说：当具体事务发生，而对何者为真正之达摩生起疑惑——尤其在需要赎罪之事上——应当把十位通晓吠陀与诸论典的婆罗门，或三位恒常研习、考察达摩者，经商议所作的结论，视为达摩。

When dharma is uncertain in a real-life situation—especially regarding expiation—one should rely on a qualified collective judgment: either ten experts in Veda and śāstra, or three dedicated specialists in dharma-study. Their considered verdict is to be treated as dharma for that case.
In the Śānti Parva’s instruction on righteous conduct, Vyāsa lays down a practical rule for resolving moral-legal ambiguity: when texts or circumstances leave doubt, consult a competent council of learned Brāhmaṇas and accept their deliberated decision as the applicable dharma.
