The Gayatri mantra is one of the most famous, chanted by millions of people every day and heralded for many reasons. But what makes it so significant? Two explanations are its Vedic origins and the meaning of the mantra itself —
That greatest Savitri is the light of the shining one we meditate on which illuminates our intellect.
The mantra, which is ‘tat savitur varenyam bhargo devasya dhimahi dhiyo yo nah prachodayat’, first appears in Rig Veda (3.62.10). When it is chanted, it is preceded by Om and the mahavyahriti: bhur bhuvah svah. They symbolise the three regions — earth, atmosphere and heaven — while Om is their source, beyond them. Similarly, the Chandogya Upanishad says about Gayatri as the personification of the mantra,
Gayatri is all this, whatever exists. Speech is the Gayatri: speech sings (gai) and protects (trai) all this that exists.[1]
