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.
