Question: What is the significance of the Gayatri mantra?

Sri Chinmoy: In India we have many mantras. In the Gita, Sri Krishna says that the Gayatri mantra is the best of all the mantras. Its meaning is: "We meditate on the transcendental glory of the Deity Supreme, who is inside the heart of the earth, inside the life of the sky, and inside the soul of the Heaven. May He stimulate and illumine our minds." It is said that if one can recite this special mantra one hundred thousand times, then all his wishes will be fulfilled. Any desire, any aspiration, no matter how mighty, will be fulfilled.
