Tengri, the Eternal Blue Sky

Nothing in the Old Turkic or early Mongol record describes a temple built for Tengri or an image made of him, and the absence looks deliberate rather than accidental once it is set beside how thoroughly settled neighboring religions, Buddhist, Manichaean and Christian communities all active along the same steppe trade routes, built exactly those things. Worship addressed to Tengri instead took place in the open, characteristically at high or otherwise marked places, with libation, the pouring out of milk or fermented mare's milk, and the burning of offerings, a pattern later observers recorded around ovoo, cairns of stones raised at passes and prominent points that travelers would add to and circle in passing, treating the sky's proper worship as an act performed under it rather than inside any enclosure built to house it.

Golden's account of Turkic religious history treats this openness as continuous with the god's own character rather than as a mark of primitiveness needing explanation. A power identified with the sky itself has no natural house to be placed inside, and steppe political theology drew directly on that absence, since a ruler's mandate came from a power no rival temple, no captured cult image and no priesthood administering access to a shrine could claim custody of. Earth and water spirits and the powers of particular localities, by contrast, were approached with the kind of localized shrine and offering practice ordinary daily religion generally involves, leaving Tengri worship itself comparatively rare in an average person's routine even while remaining foundational to political legitimacy.
