Srimad-Bhagavatam: Canto 4 - Chapter 1 - Verse 2

Sanskrit:

यदाभिषिक्तो दक्षस्तु ब्रह्मणा परमेष्ठिना ।प्रजापतीनां सर्वेषामाधिपत्ये स्मयोऽभवत् ॥ २ ॥

ITRANS:

yadābhiṣikto dakṣas tubrahmaṇā parameṣṭhināprajāpatīnāṁ sarveṣāmādhipatye smayo ’bhavat

Translation:

When Lord Brahmā appointed Dakṣa the chief of all the Prajāpatis, the progenitors of population, Dakṣa became very much puffed up.

Purport:

Although he was envious and was inimical towards Lord Śiva, Dakṣa was appointed the chief of all Prajāpatis. That was the cause of his excessive pride. When a man becomes too proud of his material possessions, he can perform any disastrous act, and therefore Dakṣa acted out of false prestige. That is described in this chapter.
