Srimad Bhagavatam Canto 09, Chapter 10, Text 14

SB 9.10.14

na tvam vayam jada-dhiyo nu vidama bhuman
 kuta-stham adi-purusam jagatam adhisam
yat-sattvatah sura-gana rajasah prajesa
 manyos ca bhuta-patayah sa bhavan gunesah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
O all-pervading Supreme Person, we are dull-minded and did not understand who You are, but now we understand that You are the Supreme Person, the master of the entire universe, the unchanging and original Personality of Godhead. The demigods are infatuated with the mode of goodness, the Prajapatis with the mode of passion, and the lord of ghosts with the mode of ignorance, but You are the master of all these qualities.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The word jada-dhiyah refers to intelligence like that of an animal. A person with such intelligence cannot understand the Supreme Personality of Godhead. Without being beaten, an animal cannot understand the purpose of a man. Similarly, those who are dull-minded cannot understand the Supreme Personality of Godhead, but when punished severely by the modes of material nature, they begin to understand Him. A Hindi poet has said:
 
duhkha se saba hari bhaje
 sukha se bhaje koi
sukha se agar hari bhaje
 duhkha kathan se haya
 
When one is distressed he goes to the church or temple to worship the Lord, but when opulent he forgets the Lord. Therefore, punishment by the Lord through material nature is necessary in human society, for without it men forget the supremacy of the Lord due to their dull, blunt intelligence.
