SRIMAD-BHAGAVATAM 8 CHAPTER 11 TEXT 25
alakṣayantas tam atīva vihvalā
vicukruśur deva-gaṇāḥ sahānugāḥ
anāyakāḥ śatru-balena nirjitā
vaṇik-pathā bhinna-navo yathārṇave
TRANSLATION
The demigods, being severely oppressed by their enemies and being unable to see Indra on the battlefield, were very anxious. Having no captain or leader, they began lamenting like traders in a wrecked vessel in the midst of the ocean.
PURPORT
From this statement it appears that in the upper planetary system there is shipping and that traders there engage in navigation as their occupational duty. Sometimes, as on this planet, these traders are shipwrecked in the middle of the ocean. It appears that even in the upper planetary system, such calamities occasionally take place. The upper planetary system in the creation of the Lord is certainly not vacant or devoid of living entities. From Śrīmad-Bhāgavatam we understand that every planet is full of living entities, just as earth is. There is no reason to accept that on other planetary systems there are no living beings.
