The Bhagavad-gita is the essence of all Vedic literatures because, after all, Vedic literature means vedais ca sarvair aham eva vedyah [Bg. 15.15], to understand Krsna, the Absolute Truth, the Supreme Personality of Godhead. That is the purpose of Vedic study. So the Supreme Personality Himself is giving the knowledge of the Supreme by Himself, personally. Therefore we are preaching this Bhagavad-gita as it is, Krsna consciousness. And the easiest method is to chant Krsna's name. Easiest method. It is recommended. It is not our manufacture. It is said.
