Rapt attention
Srimad-Bhagavatam
SB Canto 1
SB 1.3.44, Purport:
O learned brāhmaṇas, when Śukadeva Gosvāmī recited Bhāgavatam there (in the presence of Emperor Parīkṣit), I heard him with rapt attention, and thus, by his mercy, I learned the Bhāgavatam from that great and powerful sage. Now I shall try to make you hear the very same thing as I learned it from him and as I have realized it.
