Gita are the words of God

The Gita is the very life-breath, the heart, and the verbal image of the Lord. He who has his heart, speech, body and all his senses and their functions imbued with the Gita is the very embodiment of the Gita. His very sight, touch, speech and though lend supreme sanctity to others, to say nothing of those who follow his percept and example. Really speaking, no sacrifice, charity, austerity, pilgrimage, religious vow, self-restraint and fasting etc. stand comparison with the Gita.

The Gita contains words directly emanating from the lips of Bhagavan Sri Krisna. Its compiler is Maharsi Vyasa. The Lord uttered parts of His discourse in verse, which the compiler Vyasa recorded exactly as they emanated from His lips. the part of its uttered in prose was versified by the compiler, and the words of Arjuna, Sanjaya and Dhrtarastra were similarly versified by him in his own words, and divided the book of seven hundred verses into eighteen chapters, he made it an organic part of the Mahabharata. This is how the book has come down to us.

Gita and Gayatri

The Gita is superior even to the the Gayatri. Through the practice of Japa of the Gayatri man attains liberation, no doubts. But he who practices Japa of the Gayatri secures liberation only for himself; whereas the student of the Gita liberates not only himself but others as well. When the Dispenser of liberation, God Himself, becomes his own, Mukti becomes a trifling affair to him. It takes up its abode in the dust of his feet. He makes a gift of Mukti to anyone and everyone who asks for it.
If we declare the Gita as greater even than God, there will be no exaggeration. The Lord Himself says:

I take My stand on the Gita, the Gita is my supreme abode. I maintain the three worlds on the strength of the wisdom contained in the Gita.
