Gayatri....

The Gayatri mantra is one of the oldest mantras knwon to man... and its simply meaningful and hauntingly hypnotic.... especially the Deva Premal version... i like to listen to it just to wind down at night....

Om Bhur Bhuvah Svah

Tat Savitur Varenyam

Bhargo Devasya Di Mahi

Dhi Yona Prachodayat

Translation:

Throughout all of existence
"That" essential nature
illuminating existence is the
Adorable One.
May all beings perceive with subtle intellect
the magnificent brilliance of enlightened awareness.

Taken From: Shanti Mayi which i feel has the nicest translation of it...
