Gayatri Mantra

Let us meditate on God. His glorious attributes, who is the basis of everything in universe as its creator, who is fit to be worshipped as omnipresent, omnipotent, omniscient, and self-existent conscious being, who removes all ignorance and impurities from the mind and purifies and sharpens one intellect.
