Lord Kṛṣṇa first spoke Bhagavad-gītā 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-gītā, without misinterpretation, on the authority of Kṛṣṇa. To interpret Bhagavad-gītā without any reference to the will of Kṛṣṇa is the greatest offense.
