1.9.18

parāśara uvāca:
mahendro vāraṇaskandhād avatīrya tvarānvitaḥ
prasādayām āsa muniṃ durvāsasam akalmaṣam //

Descending hastily from his elephant, Mahendra endeavoured to appease the sinless Durvásas: but to the excuses and prostrations of the thousand-eyed, the Muni answered, "I am not of a compassionate heart, nor is forgiveness congenial to my nature. Other Munis may relent; but know me, Śakra, to be Durvásas. Thou hast in vain been rendered insolent by Gautama and others; for know me, Indra, to be Durvásas, whose nature is a stranger to remorse. Thou hast been flattered by Vaśisht́ha and other tender-hearted saints, whose loud praises (lave made thee so arrogant, that thou hast insulted me. But who is there in the universe that can behold my countenance, dark with frowns, and surrounded by my blazing hair, and not tremble? What need of words? I will not forgive, whatever semblance of humility thou mayest assume."
