SB 10.76.22
kvacid bhumau kvacid vyomni
giri-murdhni jale kvacit
alata-cakra-vad bhramyat
saubham tad duravasthitam
Translation:
From one moment to the next the Saubha airship appeared on the earth, in the sky, on a mountain peak or in the water. Like a whirling, flaming baton, it never remained in any one place.
