To interpret Bhagavad-gītā without any reference to the will of Kṛṣṇa 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 Kṛṣṇa's first disciple. Such understanding of Bhagavad-gītā is really profitable and authorized for the welfare of human society in fulfilling the mission of life.
