Aum bhur bhuvah swah, tat savitur varenvam.
Bhargo devasya dhimahi, dhiyo yo nah prochodayay.
The four-part mantra is addressed to God (Aum) and the translation goes like this:
Oh God, you are the giver of life, you can free us from all the pains, you are present all over, you give happiness, you are the creator of this universe and beyond. We humbly submit to You and concentrate on your pious, sin-quelling and pervading ENERGY.
This ENERGY produced and released by You illuminates our mental faculties. We seek from you that this Energy resides in all our thinking processes so our thoughts are always inspired to undertake only those actions which can lead us to be on the path of righteousness.
