14.1.4.9

apaśyaṃ gopāmanipadyamānamiti eṣa vai gopā ya eṣa tapatyeṣa hīdaṃ sarvaṃ gopāyatyatho na nipadyate tasmādāhāpaśyam gopāmanipadyamānamiti

[Vâg. S. XXXVII, 17; Rig-v. I, 164, 31; X, 177, 3,] 'I beheld the guardian, the never-resting,'--he who shines yonder is indeed the guardian, for he guards everything here; and he does not lie down to rest: therefore he says, 'I beheld the guardian, the never-resting;'-- 10, 'Wandering on paths hither and thither,'--for he indeed wanders hither and thither on the divine paths;--'arraying himself in the gathering and the radiating,'--for he indeed arrays himself in the gathering (converging) and the radiating regions, or rays;--'he moveth to and fro within the spheres,'--for again and again he wanders moving within these worlds.
