Every Gayatri Mantra has a revealing Prophet or Rishi and a presiding Deity Adhishthana Devata, who is the subject of the Mantra. This Mantra is expressed through the inner workings of Sri Sathya Sai through Pandit Sri Gandikota Subrahmanya Sastry in the presence of Sri Sathya Sai Baba. Needless to say that Swami Himself is the presiding Deity of this Veda Mantra.
Mantra with Meaning :
Om Saeeshwaraya Vidmahe - We know Sri Sathya Sai as Supreme Divinity Incarnate
Sathya Devaya Dheemahi - We meditate on this God of Truth
Thannah Sarvah Prachodayath || - May Almighty God lead us to Liberation ||
This Sri Sathya Sai Gayathri, like other Gayathris, is on a par with Veda Mantra or mystic formula. It has 24 letters; it consists of three lines, each with 8 letters. Such a composition has unique properties. According to Maharshi Vararuchi, the numerology of all letters adds up to 108. That is why recitation is to be done 108 times; to realize the full effect of Siddhi-which is signified by the 108th number, i.e. the Meru or the tassel of a rosary or Japamala. Ashtottara Sata Nama—the 108 name chantings lead to the realization of God, which is the goal.
