Nārāyaṇa-tejas: Kṛṣṇa’s Vrata, the Fire-Manifestation, and the Sages’ Inquiry (अनुशासन पर्व, अध्याय १२६)
सुरापो5सम्मतादायी भ्रूणहा गुरुतल्पग: । तपसा तरते सर्वमेनसश्न प्रमुच्यते
surāpo 'sammatadāyī bhrūṇahā gurutalpagaḥ | tapasā tarate sarvam enasaś ca pramucyate ||
Seorang peminum minuman keras, pemberi sedekah yang tidak disahkan, pembunuh janin, dan pelanggar ranjang guru—bahkan orang seperti itu pun, melalui tapa, dapat menyeberangi seluruh dosa dan terbebas dari rasa bersalah.
भीष्म उवाच
The verse teaches that even the gravest moral transgressions can be overcome through tapas (austerity/penance), implying the possibility of purification and ethical restoration when disciplined expiation is undertaken.
In Anuśāsana Parva, Bhīṣma is instructing on dharma and the means of atonement. Here he lists severe offenses and asserts that austerity can enable one to cross beyond sin and be freed from guilt.
