Srimad-Bhagavatam: Canto 6 - Chapter 1 - Verse 18

Sanskrit:

यथा ससर्ज भूतानि दक्षो दुहितृवत्सल: ।रेतसा मनसा चैव तन्ममावहित: श‍ृणु ॥ १८ ॥

ITRANS:

yathā sasarja bhūtānidakṣo duhitṛ-vatsalaḥretasā manasā caivatan mamāvahitaḥ śṛṇu

Translation:

Śukadeva Gosvāmī continued: Please hear from me with great attention how Prajāpati Dakṣa, who was very affectionate to his daughters, created different types of living entities through his semen and through his mind.

Purport:

The word duhitṛ-vatsalaḥ indicates that all the prajās were born from Dakṣa’s daughters. Śrīla Viśvanātha Cakravartī Ṭhākura says that apparently Dakṣa had no son.
