Srimad-Bhagavatam: Canto 9 - Chapter 1 - Verse 2
तस्य सोद्यममावीक्ष्य पादस्पर्शविलज्जित: ।अस्तावीत् तद्धरेरस्त्रं कृपया पीडितो भृशम् ॥ २ ॥
tasya sodyamam āvīkṣyapāda-sparśa-vilajjitaḥastāvīt tad dharer astraṁkṛpayā pīḍito bhṛśam
When Durvāsā touched his lotus feet, Mahārāja Ambarīṣa was very much ashamed, and when he saw Durvāsā attempting to offer prayers, because of mercy he was aggrieved even more. Thus he immediately began offering prayers to the great weapon of the Supreme Personality of Godhead.
