Srimad-Bhagavatam: Canto 8 - Chapter 1 - Verse 39
Sanskrit:
बलान्महेन्द्रस्त्रिदशा: प्रसादा-न्मन्योर्गिरीशो धिषणाद् विरिञ्च: ।खेम्यस्तुछन्दांस्यृषयो मेढ्रत: क:प्रसीदतां न: स महाविभूति: ॥ ३९ ॥
ITRANS:
balān mahendras tri-daśāḥ prasādānmanyor girīśo dhiṣaṇād viriñcaḥkhebhyas tu chandāṁsy ṛṣayo meḍhrataḥ kaḥprasīdatāṁ naḥ sa mahā-vibhūtiḥ
Translation:
Mahendra, the King of Heaven, was generated from the prowess of the Lord, the demigods were generated from the mercy of the Lord, Lord Śiva was generated from the anger of the Lord, and Lord Brahmā from His sober intelligence. The Vedic mantras were generated from the bodily holes of the Lord, and the great saints and prajāpatis were generated from His genitals. May that supremely powerful Lord be pleased with us.
