Kāliya-damana: Kṛṣṇa Subdues the Serpent and Purifies the Yamunā
श्रीशुक उवाच विलोक्य दूषितां कृष्णां कृष्ण: कृष्णाहिना विभु: । तस्या विशुद्धिमन्विच्छन् सर्पं तमुदवासयत् ॥ १ ॥
śrī-śuka uvāca vilokya dūṣitāṁ kṛṣṇāṁ kṛṣṇaḥ kṛṣṇāhinā vibhuḥ tasyā viśuddhim anvicchan sarpaṁ tam udavāsayat
Sinabi ni Śukadeva: Nang makita ng Panginoong Śrī Kṛṣṇa, ang Kataas-taasang Persona ng Diyos, na nadungisan ang Ilog Yamunā ng maitim na ahas na si Kāliya, ninais Niyang dalisayin ang ilog at kaya pinalayas Niya ang ahas mula roon.
This verse states that Krishna, seeing the Yamuna polluted by the black serpent Kaliya, acted to restore her purity by driving the serpent away.
Because Kaliya’s presence was contaminating the Yamuna; Krishna sought the river’s purification and the removal of the source of that defilement.
It teaches that devotion includes protecting what is sacred and removing harmful influences—beginning with cleansing one’s own habits, environment, and intentions.
