Gayatri Mantra (the mother of the Vedas) is the foremost mantra in Hinduism.Its meaning is that "May the Almighty God illuminate our intellect to lead us along the righteous path".
AUM BHOOR BHUWAH SWAHA,
TAT SAVITUR VARENYAM
BHARGO DEVASAYA DHEEMAHI
DHIYO YO NAHA PRACHODAYAT.
Oh God! You are the giver of life,
Remover of pain and sorrow,
The bestower of happiness,
Oh! creator of the universe,
May we receive your supreme sin-destroying light,
May you guide our intellect in the right direction.
