Śrī Śukadeva Gosvāmī said: Thus the chief of the sages, who was always enthusiastic about describing topics regarding the Personality of Godhead, began to narrate the descriptive explanation of the Purāṇas, being so infused by Vidura. He was very much enlivened by speaking on the transcendental activities of the Lord.
