Translation:
O subduer of the enemy, I travel throughout the surface of the earth learning constantly about the nature of this world, and thus I personally witnessed the lesson of the young girl.
Purport:
The brahmana sage here explains to King Yadu that he is not presenting theoretical knowledge. Rather, by wandering throughout the world the observant and thoughtful brahmana has personally experienced the lessons learned from all of the above-mentioned gurus. Thus, instead of posing himself to be omniscient like God, he humbly explains that he has faithfully learned these lessons in his travels.
