Śatapatha Brāhmaṇa ("of a hundred paths") 7.3.1.1

7.3.1.1

cito gārhapatyo bhavati | acita āhavanīyo 'tha rājānaṃ krīṇātyayaṃ vai loko gārhapatyo dyaurāhavanīyo 'tha yo 'yaṃ vāyuḥ pavata eṣa soma etaṃ tadimau lokāvantareṇa dadhāti tasmādeṣa imau lokāvantareṇa pavate

Built is the Gârhapatya, unbuilt the Âhavanîya; he then buys the king (Soma): the Gârhapatya being this (terrestrial) world, the Âhavanîya the sky, and Soma he that blows yonder, he thus places him (Vâyu, the wind) between these two worlds; and hence he blows between these two worlds.
