Gayatri Mantra:-

ॐ भूर्भुवः स्वः तत्सवितुर्वरेण्यं भर्गो देवस्यः धीमहि धियो यो नः प्रचोदयात्॥

Om Bhur Bhuwah Svah Tat Savitur Varenyam
Bhargo Devasya Dhimahi Dhiyo Yo Nah Prachodayat॥

Translation of the Mantra

Let us adore the supremacy of that divine sun, the god-head who illuminates all, who recreates all, from whom all proceed, to whom all must return, whom we invoke to direct our understandings aright in our progress toward his holy seat.
