Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 1


श्रीशुक उवाचअथ कृष्णश्च रामश्च कृतशौचौ परन्तप । मल्लदुन्दुभिनिर्घोषं श्रुत्वा द्रष्टुमुपेयतु: ॥ १ ॥


śrī-śuka uvācaatha kṛṣṇaś ca rāmaś cakṛta-śaucau parantapamalla-dundubhi-nirghoṣaṁśrutvā draṣṭum upeyatuḥ


Śukadeva Gosvāmī said: O chastiser of enemies, Kṛṣṇa and Balarāma, having executed all necessary purification, then heard the kettledrums resounding at the wrestling arena, and They went there to see what was happening.


Śrīla Śrīdhara Svāmī explains the words kṛta-śaucau, “having executed all necessary purification,” as follows: “Two days previously, Kṛṣṇa and Balarāma had executed Their purification, Their relief from offense [by performing heroic deeds]. The Lords reasoned: ‘Even after We have made Our power known by breaking the bow and by performing other feats, Our parents have still not secured freedom. Kaṁsa is again trying to kill them. Therefore, although he is Our maternal uncle, it will not be wrong for Us to kill him.’ They assured Their offenselessness by this reasoning.”
