The Gayatri Mantra is an ancient verse from the Rig Veda (3.62.10). It is a prayer to Savitr (the Cosmic Sun), representing the source of all life and consciousness. Chanting Gayatri mantra is a science. It is not just a prayer, but a specific rhythmic alignment with the Supreme Light of Self for illumination of the intellect—asking the Divine light to clarify our minds so we may perceive Supreme truth with clarity, in every moment, here and now.
It is chanted in a specific sequence of syllables arranged in a rhythmic pattern (chhanda) that, when chanted, produces precise acoustic vibrations. These vibrations are observed to stimulate the hypothalamus (which controls immunity and hormone release) and the vagus nerve, inducing a physiological state of "restful alertness".
Introduction
The Gayatri Mantra (Rigveda 3.62.10) is one of the oldest known Sanskrit hymns, consisting of 24 syllables addressed to Savitr, the solar deity symbolizing divine illumination. Its traditional recitation is believed to stimulate intellect (medha) and foster spiritual awakening.

Since the early 2000s, an increasing number of peer-reviewed studies—primarily from India—have investigated the psychological, cognitive, physiological, and neurobiological effects of regular Gayatri Mantra chanting. This review synthesizes all verifiable, published research as of December 2025, focusing exclusively on studies that used the authentic Gayatri Mantra as the primary intervention.
