SB 9.5.22
sri-suka uvaca
evam sankirtya rajanam
durvasah paritositah
yayau vihayasamantrya
brahmalokam ahaitukam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sri Sukadeva Gosvami continued: Thus being satisfied in all respects, the great mystic yogi Durvasa took permission and left, continuously glorifying the King. Through the skyways, he went to Brahmaloka, which is devoid of agnostics and dry philosophical speculators.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Although Durvasa Muni went back to Brahmaloka through the spaceways, he did not need an airplane, for great mystic yogis 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 Durvasa Muni, the great mystic yogi, 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. Durvasa 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 jñanis and yogis cannot compare to a devotee.
