yadābhiṣikto dakṣas tu
brahmaṇā parameṣṭhinā
prajāpatīnāṁ sarveṣām
ādhipatye smayo 'bhavat
yadā - when; abhiṣiktaḥ - appointed; dakṣaḥ - Dakṣa; tu - but; brahmaṇā - by Brahmā; parameṣṭhinā - the supreme teacher; prajāpatīnām - of the Prajāpatis; sarveṣām - of all; ādhipatye - as the chief; smayaḥ - puffed up; abhavat - he became.
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.
