Vibhūti-yoga in the Bhāgavata: The Lord’s Manifest Opulences and the Discipline of Control
तीर्थानां स्रोतसां गङ्गा समुद्र: सरसामहम् । आयुधानां धनुरहं त्रिपुरघ्नो धनुष्मताम् ॥ २० ॥
tīrthānāṁ srotasāṁ gaṅgā samudraḥ sarasām aham āyudhānāṁ dhanur ahaṁ tripura-ghno dhanuṣmatām
Entre os tīrthas e as correntes que fluem, Eu sou a sagrada Gaṅgā que purifica; e entre as águas serenas, Eu sou o oceano. Entre as armas, Eu sou o arco; e entre os arqueiros, Eu sou o Senhor Śiva, destruidor de Tripura.
Lord Śiva used his bow to completely cover with arrows the three demoniac cities built by Maya Dānava.
In this verse, Krishna identifies the Gaṅgā as His own manifestation among sacred rivers, teaching that contact with the Gaṅgā is revered because it powerfully reminds devotees of the Lord’s presence and purity.
Krishna is describing His vibhūtis—His prominent manifestations—so He cites Śiva as Tripuraghna, famed for destroying Tripura with divine archery, showing that all extraordinary power and glory ultimately rest on the Lord.
Practice remembrance by linking greatness to Krishna: when you see a mighty river, the ocean, or exceptional skill, consciously recall that such excellence is a sign of the Supreme, strengthening gratitude and devotion.
