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.
The Kṛṣṇa consciousness movement is essential in human society, for it offers the highest perfection of life. How this is so is explained fully in the Bhagavad-gītā. Unfortunately, mundane wranglers have taken advantage of Bhagavad-gītā to push forward their demonic propensities and mislead people regarding right understanding of the simple principles of life.
