Madhvaon Brahma Sūtra 3.1.8

From the Kashayana Sruti, “ From Smoke he goes to Cloud, from Cloud to Ether, from Ether to the sphere of the Moon, and returns up to Ether as he went; (then) from Ether to Vayu; and having been Yayu, he becomes Smoke j and having been Smoke, he becomes Cloud j and having been Cloud he becomes Megha (the Cloud) and having become Megha (the Cloud), pours down (descends with rain),” it is evident; he descends by the route by which he went (to a certain stage and then) by a different route.
