Matsya Purana — Brahmā’s Four Faces
आकाशविकृतेर् वायुः शब्दस्पर्शगुणो ऽभवत् वायोश् च स्पर्शतन्मात्रात् तेजश् चाविर् अभूत् ततः //
ākāśavikṛter vāyuḥ śabdasparśaguṇo 'bhavat vāyoś ca sparśatanmātrāt tejaś cāvir abhūt tataḥ //
From the modification of ether (ākāśa) arose wind (vāyu), endowed with the qualities of sound and touch. And from wind—through the subtle essence (tanmātra) of touch—fire (tejas) then manifested.
It presents the creation-side sequence of elemental evolution: ether transforms into air (adding touch to sound), and from air’s touch-subtlety fire manifests—an ordered cosmology that is later reversed conceptually during dissolution.
Indirectly, it grounds dharma in cosmic order: the same structured progression (cause → subtle essence → manifest form) is a model for disciplined governance and household life—actions should follow proper sequence, restraint, and intelligible causality.
The verse itself is cosmological, but its element-theory underlies Vāstu and ritual logic: fire (tejas) is derived through touch-subtlety and becomes central to homa/agnikārya and to Vāstu considerations of heat, light, and the placement/function of the fire-space (agni).
