आयुधानां धनुरहं त्रिपुरघ्नो धनुष्मताम् ॥ २० ॥
samudraḥ sarasām aham
āyudhānāṁ dhanur ahaṁ
Among sacred and flowing things I am the holy Ganges, and among steady bodies of water I am the ocean. Among weapons I am the bow, and of the wielders of weapons I am Lord Śiva.
Lord Śiva used his bow to completely cover with arrows the three demoniac cities built by Maya Dānava.
