The Bhagavad Gita, the most sacred scripture of the Hindus, is a portion of the great epic work the Mahabharata, which was composed by Sage Vyasa many centuries before Christ. The Bhagavad Gita presents a dynamic picture of spiritual life. It does not advocate a passive withdrawal from the world in search of spiritual peace and perfection. Rather, it beckons the soul of a person to fight the “battle of life" heroically.
There is a royal secret by which one may attain Liberation even in this very life. The secret lies in relinquishing everything to God. A devotee should surrender not only all his actions, but also his innermost thoughts at the Feet of the Lord—this includes not only the positive thoughts, but also the impurities of his heart. This is the secret of spiritual transformation.
