महारुद्रस्सद्यः स खलु दितिजेनातिगिलितस्ततश्चासौ नन्दी निशितशरशूलासिसहितः ।। प्रधानो योधानां मुनिवरशतानामपि महान्निवासो विद्यानां शमदममहाधैर्यसहितः।।२३।।

sanskrit

That great Rudra (Mahārudra) was at once swallowed by the Daitya (demon); Then Nandī, armed with sharp arrows, spears, and swords, arose. He was the chief among warriors and even among hundreds of great sages, the abode of all knowledge, endowed with tranquility, self-control, and supreme courage.
