Prāyaścitta for Mahāpātakas and the Sin-destroying Power of Viṣṇu-smaraṇa
हत्वा त्वनुपनीतांश्च तथा पादव्रतं चरेत् । हत्वा तु क्षत्रियं विप्रः षडब्दं कुच्छ्रमाचरेत् ॥ २० ॥
hatvā tvanupanītāṃśca tathā pādavrataṃ caret | hatvā tu kṣatriyaṃ vipraḥ ṣaḍabdaṃ kucchramācaret || 20 ||
若杀害尚未受入门礼(upanayana)者,应修行“足分誓”(pāda-vrata)以作忏悔。若婆罗门(brāhmaṇa)杀害刹帝利(kṣatriya),则当行 kṛcchra 苦行六年。
Sage Nārada (teaching prāyaścitta norms within dharma instruction)
Vrata: pāda-vrata; kṛcchra
Primary Rasa: shanta
Secondary Rasa: karuna
It frames prāyaścitta as a dhārmic means to acknowledge wrongdoing, restrain the senses through vrata/austerity, and restore moral-spiritual order after a grave transgression.
Indirectly: by prescribing purification through vrata and disciplined living, it supports inner purity (śuddhi) that is considered foundational for steady worship and devotion.
Kalpa (ritual discipline) is implied—specifically the regulation of vows (vrata) and penances (kṛcchra) as part of dharma-oriented ritual procedure.
