tat savitur vareṇiyaṃ
That sun most excellent

bhargo devasya dhīmahi |
on the radiance of the Divine I meditate |

dhiyo yo naḥ pracodayāt ||
wisdom may (that radiance) our impel |

“I meditate on the divine radiance

of the most excellent sun.

May it impel my wisdom.”

Note:
Gāyatrī is a particular ancient metre or rhythmic pattern of twenty-four syllables generally composed as a triplet of three lines with eight syllables in each line.
Hence T Krishnamacharya’s view that Om is not a component part of this Mantra, though it may be added as an accompaniment if appropriate, according to the students background, interest and understanding.
