Gayatri is the mantra which imparts true wisdom. It inspires the mind, intellect inner psyche and emotions of the devotee towards the righteous path. Its Sadhana helps in progressive growth of righteous(sat) elements. When the Sadhak concentrates on the meaning of this mantra he realises that the supreme prosperity and the greatest success in life is to attain true wisdom. When he gets fully convinced about the true aim of life, he single-minded starts his self-effort towards this goal. This aspiration creates an ever expanding vibrations in the universal realm which attracts and assimilates waves of righteous thoughts, emotions and inspirations pervading the subtle atmosphere. The magnetic power of thoughts is well-known. Thoughts at tract thoughts of similar kind scattered in the mental universe with the result that powerful eternal thoughts and spiritual attainments of living and past illumined persons start accumulating spontaneously within the Sadhak as a divine boon and his accumulated capital of such thoughts goes on increasing.
The effect of this influx of righteousness (satogun) in the body and mind is amazing. This is not visible to the naked eye nor can it be understood from purely physical point of view. But those who are endowed with the occult knowledge of the working of the inner being know it well that decrease in the elements of tam and raj and increase in sat is almost similar to the steady process of elimination of disease producing toxins, viruses and germs from the body and replacing them with health-giving rejuvenating cells. True, the process will not be instantly visible, but there can be no doubt that it will have miraculous effects on health in due course. Rejuvenation of body is a scientifically proved phenomenon. Whether this benefit is a divine gift or it is due to human efforts is a matter on which opinion may differ but it is certain that Gayatri Sadhana increases virtues in the inner psyche of the Sadhak and simultaneously throws out the vices and impurities. This results in internal transformation of the Sadhak. There is no use in entering into the controversy whether the advantage accrued is an individual attainment or a divine boon. No work, whatsoever, can be accomplished without the grace of God and so it may be said that all that happens is due to Divine grace.
