Srimad-Bhagavatam: Canto 9 - Chapter 1 - Verse 22
श्रीशुक उवाचएवं सङ्कीर्त्य राजानं दुर्वास: परितोषित: ।ययौ विहायसामन्त्र्य ब्रह्मलोकमहैतुकम् ॥ २२ ॥
śrī-śuka uvācaevaṁ saṅkīrtya rājānaṁdurvāsāḥ paritoṣitaḥyayau vihāyasāmantryabrahmalokam ahaitukam
Śrī Śukadeva Gosvāmī continued: Thus being satisfied in all respects, the great mystic yogī Durvāsā took permission and left, continuously glorifying the King. Through the skyways, he went to Brahmaloka, which is devoid of agnostics and dry philosophical speculators.
Although Durvāsā Muni went back to Brahmaloka through the spaceways, he did not need an airplane, for great mystic yogīs can transport themselves from any planet to any other without any machine. There is a planet named Siddhaloka whose inhabitants can go to any other planet because they naturally have all the perfection of yoga practice. Thus Durvāsā Muni, the great mystic yogī, could go through the skyways to any planet, even to Brahmaloka. In Brahmaloka, everyone is self-realized, and thus there is no need of philosophical speculation to come to the conclusion of the Absolute Truth. Durvāsā Muni’s purpose in going to Brahmaloka was apparently to speak to the residents of Brahmaloka about how powerful a devotee is and how a devotee can surpass every living entity within this material world. The so-called jñānīs and yogīs cannot compare to a devotee.
