Satya Sai Gayatri Mantra

Sri Sathya Saibaba Mantras:
Om Saayeeshvaraaya Vidhmahe
Sathya Dhevaaya Dheemahi
Thannassarvah Prachodayaath
The meaning of this is:
"I know through Gurus and Shastras (and by direct experience) that Sai is God Himself: He is Bhagavan and Iswara. I meditate on this form in my heart with all my mental faculties. He is the embodiment of truth, divinity, universal consciousness and one who pervades all the worlds. I pray to such a Saiparameswar to direct our intellects to engage in auspicious and righteous activities. I meditate on this great form."
This Sathya Sai Gayathri, like other Gayathris, is on par with Veda Mantra or mystic formula. It has 24 letters; it consists of three lines, each with eight letters. Such a composition has unique properties. According to Maharishi 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. Meru or the tassel of a rosary or Japamala. Ashtottara Sata Nama - the 108 name-chanting leads to the realization of God, which is the goal.
