Our only purpose is to present this Bhagavad Gita As It Is in order to guide the conditioned student to the same purpose for which Krsna descends to this planet once in a day of Brahma, or every 8,600,000,000 years. This purpose is stated in Bhagavad Gita, and we have to accept it as it is; otherwise there is no point in trying to understand the Bhagavad Gita and its speaker, Lord Krsna. Lord Krsna first spoke Bhagavad Gita to the sun-god some hundreds of millions of years ago. We have to accept this fact and thus understand the historical significance of Bhagavad Gita, without misinterpretation, on the authority of Krsna. To interpret Bhagavad Gita without any reference to the will of Krsna is the greatest offense. In order to save oneself from this offense, one has to understand the Lord as the Supreme Personality of Godhead, as He was directly understood by Arjuna, Lord Krsna's first disciple. Such understanding of Bhagavad Gita is really profitable and authorized for the welfare of human society in fulfilling the mission of life.
