SB 1.13.60
ity uktvatharuhat svargam
naradah saha-tumburuh
yudhisthiro vacas tasya
hrdi krtvajahac chucah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Having spoken thus, the great sage Narada, along with his vina, ascended into outer space. Yudhisthira kept his instruction in his heart and so was able to get rid of all lamentations.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sri Naradaji is an eternal spaceman, having been endowed with a spiritual body by the grace of the Lord. He can travel in the outer spaces of both the material and spiritual worlds without restriction and can approach any planet in unlimited space within no time. We have already discussed his previous life as the son of a maidservant. Because of his association with pure devotees, he was elevated to the position of an eternal spaceman and thus had freedom of movement. One should therefore try to follow in the footsteps of Narada Muni and not make a futile effort to reach other planets by mechanical means. Maharaja Yudhisthira was a pious king, and therefore he could see Narada Muni occasionally; anyone who desires to see Narada Muni must first be pious and follow in the footsteps of Narada Muni.
Thus end the Bhaktivedanta purports of the First Canto, Thirteenth Chapter, of the Srimad-Bhagavatam, entitled “Dhrtarastra Quits Home.”
