The Gayatri mantra has been translated in many ways. It is dedicated to Savitr, the sun deity or the one supreme creator light (not the physical sun in our solar system, but the sun of truth in the spiritual heavens).
"We meditate on the glory of that Being who has produced this universe; may He enlighten our minds." – Swami Vivekananda
