The Bhagavad Gita is unique among religious texts in its emphasis on the discharge of everyday duties, irrespective of their nature, as an effective discipline for the realization of God. The Gita teaches that if a man performs his duties, surrendering the fruit to God and discarding all selfish motives, he gains purity of heart and achieves ultimate liberation. It is knowledge of God that gives man the strength to face calmly and cheerfully the duties of life. The Gita shows the way to spiritualize life and illumine even its drab and gray phases with the radiance of the Spirit. It lays down practical spiritual disciplines that can be followed by all, irrespective of faith and creed.
