Matsya Purana — Brahmā–Gāyatrī as a Divine Pair and the Early Genealogies of Creation
यथातपो न रहितश् छायया दृश्यते क्वचित् गायत्री ब्रह्मणःपार्श्वं तथैव न विमुञ्चति //
yathātapo na rahitaś chāyayā dṛśyate kvacit gāyatrī brahmaṇaḥpārśvaṃ tathaiva na vimuñcati //
Just as the sun is never seen anywhere without its shadow, so too does Gāyatrī never leave the side of Brahmā.
Indirectly, it frames creation as powered by Brahmā together with his śakti—Gāyatrī—implying that cosmic origination is not merely an act of a deity but of an inseparable divine potency.
It supports daily Gāyatrī-japa and Sandhyā practice: as Gāyatrī is bound to Brahmā (creative order), the householder sustains dharma and clarity of intellect by remaining ‘inseparably’ connected to Gāyatrī through disciplined recitation.
Ritually, it elevates Gāyatrī as a central mantra-shakti for worship and purification; while not a Vāstu rule, it underpins temple and domestic rites where Gāyatrī recitation consecrates actions and offerings.
