Srimad Bhagavatam Canto 06, Chapter 04, Text 41

SB 6.4.41

na kiñcanodirayitum
 asakat tivraya muda
apurita-manodvarair
 hradinya iva nirjharaih
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
As rivers are filled by water flowing from a mountain, all of Daksa’s senses were filled with pleasure. Because of his highly elevated happiness, Daksa could not say anything, but simply remained flat on the ground.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
When one actually realizes or sees the Supreme Personality of Godhead, he is filled with complete happiness. For example, when Dhruva Maharaja saw the Lord in his presence, he said, svamin krtartho ’smi varam na yace: “My dear Lord, I have nothing to ask from You. Now I am completely satisfied.” Similarly, when Prajapati Daksa saw the Supreme Lord in his presence, he simply fell flat, unable to speak or ask Him for anything.
