Explanation of the Mantra:

Gayatri is the embodiment of all forms of Godhead - Sarva Devatha Swaroopam. Gayatri does not belong to any caste, to any sect or to any religion as such. It is universal in its scope.
Gayatri has nine important attributes. These are:

  1. Aum : Sound as the basis of Creation, Brahman
  2. Bhuh : The Earth, the gross
  3. Bhuvah : The Atmosphere, the Ether, the Subtle.
  4. Suvah : Heaven, the region beyond Bhuvah the Causal.
  5. Tat : Stands for That. The Ultimate Reality is simply referred to as That because it defies description through speech or language.
  6. Savitur : Stands for Divine Savitri, equated with the vivifying power contained within the Sun.
  7. Varenyum: Adore
  8. Bhargo : Radiance, Lustre, Illumination
  9. Devasya : Divine Radiance or Grace.
