Kṛṣṇa Kills Dantavakra; Balarāma’s Pilgrimage and the Slaying of Romaharṣaṇa
ततश्च भारतं वर्षं परीत्य सुसमाहित: । चरित्वा द्वादश मासांस्तीर्थस्नायी विशुध्यसि ॥ ४० ॥
tataś ca bhārataṁ varṣaṁ parītya su-samāhitaḥ caritvā dvādaśa-māsāṁs tīrtha-snāyī viśudhyasi
Thereafter, for twelve months, You should circumambulate the land of Bhārata in a mood of serious meditation, executing austerities and bathing at various holy pilgrimage sites. In this way You will become purified.
Śrīla Jīva Gosvāmī points out that the word viśudhyasi means that Lord Balarāma would achieve spotless fame by setting such a perfect example for the people in general.
This verse states that traveling throughout Bhārata-varṣa with a composed mind and bathing in sacred tīrthas for a year brings purification.
Within the Syamantaka-related narrative, Kṛṣṇa indicates a dhārmic process of atonement and cleansing—undertaken with mental discipline—so the person involved may become purified and socially/spiritually restored.
Combine outer spiritual practices (pilgrimage, sacred visits, vows) with inner steadiness (susamāhitaḥ): intentional time for sādhana, self-reflection, and disciplined living to cleanse habits and conscience.
