SB 1.13.60, Translation and Purport

Having spoken thus, the great sage Nārada, along with his vīṇā, ascended into outer space. Yudhiṣṭhira kept his instruction in his heart and so was able to get rid of all lamentations.

Śrī Nāradajī 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 Nārada Muni and not make a futile effort to reach other planets by mechanical means. Mahārāja Yudhiṣṭhira was a pious king, and therefore he could see Nārada Muni occasionally; anyone who desires to see Nārada Muni must first be pious and follow in the footsteps of Nārada Muni.
