1.3.35.46

śraddhāṃ vihāya paramāṃ śivapūjakānāṃ niṃdāparaḥ sa hi babhūva narādhamaśca..
sarvairmaharṣibhirupetya sa tatra śarvaṃ devaṃ nininda na babhūva kadāpi śāntaḥ.. 1.46 ..

Abandoning supreme faith, that lowest of men became intent on censuring the worshippers of Śiva;
approaching there with all the great seers, he reviled the god Śarva and never became tranquil.
