The Gāyatrī Mantra is dedicated to Savitr, a Vedic Sun deity. First is an English translation of the Gayatri prayer (addressed to the sun)
“You, who are the source of all power,
Whose rays illuminate the whole world,
Illuminate also my heart
So that it too can do Your work.” [1]
Gayatri is the Mother of all scriptures (Vedas). She is present, wherever Her name is chanted. She is very powerful. The One who nourishes the individual being is Gayatri. She bestows pure thoughts on anyone who worships Her. She is the embodiment of all Goddesses. Our very breath is Gayatri, our faith in existence is Gayatri. Gayatri has five faces, they are the five life principles. She has nine descriptions, they are ‘Om, Bhur, Bhuvah, Swah, Tat, Savitur, Vareñyaṃ, Bhargo, Devasya’. Mother Gayatri nourishes and protects every being and she channelizes our senses in the proper direction. ‘Dhīmahi’ means meditation. We pray to her to inspire us with good intelligence. ‘Dhīyo Yonah Prachodayāt’ – We beseech her to bestow on us everything we need. Thus Gayatri is a complete prayer for protection, nourishment and finally, liberation. – ‘My Dear Students’, Vol 3, Ch 2, Mar 19, 1998 [2]
