In plain words
The poet, of Śrīraṅgam: Māl, the first cause, [as Kṛṣṇa] made the three-eyed one [Śiva] flee headlong from the fierce battle, with Kālī, who had incurred a curse and was shameful to look on, and with his sons and his gathered army; and he cut off Bāṇa's thousand arms. His great temple, rich in waters, bears the name of Araṅgam.
