SB 10.89.2
tasya jijñasaya te vai
bhrgum brahma-sutam nrpa
taj-jñaptyai presayam asuh
so ’bhjagad brahmanah sabham
Translation:
Eager to resolve this question, O King, the sages sent Lord Brahma’s son Bhrgu to find the answer. First he went to his father’s court.
Purport:
As Srila Prabhupada explains in Krsna, the Supreme Personality of Godhead: “The plan decided upon by the sages was for Bhrgu to test which one of the predominating deities possessed the quality of goodness in full.” One who is in the mode of goodness possesses such qualities as tolerance and equanimity, whereas those conducted by the modes of passion and ignorance are prone to easily lose their temper.
