This absolute position of Kṛṣṇa is difficult to understand for any person who is not a devotee of Kṛṣṇa in the system of paramparā (disciplic succession). Generally the so-called scholars, politicians, philosophers, and svāmīs, without perfect knowledge of Kṛṣṇa, try to banish or kill Kṛṣṇa when writing commentary on Bhagavad-gītā. Such unauthorized commentary upon Bhagavad-gītā is known as Māyāvāda-bhāṣya, and Lord Caitanya has warned us about these unauthorized men. Lord Caitanya clearly says that anyone who tries to understand Bhagavad-gītā from the Māyāvādī point of view will commit a great blunder. The result of such a blunder will be that the misguided student of Bhagavad-gītā will certainly be bewildered on the path of spiritual guidance and will not be able to go back to home, back to Godhead.
Our only purpose is to present this Bhagavad-gītā As It Is in order to guide the conditioned student to the same purpose for which Kṛṣṇa descends to this planet once in a day of Brahmā, or every 8,600,000,000 years. This purpose is stated in Bhagavad-gītā, and we have to accept it as it is; otherwise there is no point in trying to understand the Bhagavad-gītā and its speaker, Lord Kṛṣṇa. 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. 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.
