A famous quote in Sanskrit brings to surface the efficacy of Shree Gayatri Mantra. It goes thus, “Gayan Trayate Iti Gayatri”, meaning Gayatri is the protector of those who chant it. Gayatri is called the mother of all mantras. In the Hindu pantheism, a lot of importance is given to Vedic chantings as they carry a lot of positive vibrations that are highly beneficial to enhancing the physical, mental and spiritual health of a person.

The Gayatri mantra is one of the oldest and most powerful of Sanskrit mantras. It is believed that by chanting the Gayatri mantra and firmly establishing it in the mind, if you carry on your life and do the work that is ordained for you, your life will be full of happiness.

The word "Gayatri" itself explains the reason for the existence of this mantra. It has its origin in the Sanskrit phrase Gayantam Triyate iti, and refers to that mantra which rescues the chanter from all adverse situations that may lead to mortality.
Goddess Gayatri is also called "Veda-Mata" or the Mother of the Vedas - Rig, Yajur, Saam and Atharva - because it is the very basis of the Vedas. It is the basis, the reality behind the experienced and the cognized universe.

The Gayatri mantra is composed of a metre consisting of 24 syllables - generally arranged in a triplet of eight syllables each. Therefore, this particular meter (tripadhi) is also known as the Gayatri Meter or "Gayatri Chhanda."
