Therefore Bhagavad-gītā should be taken up in a spirit of devotee of Lord Śrī Kṛṣṇa. One should not think that he is equal, on the same level of Śrī Kṛṣṇa, or one should not think that He is an ordinary personality, maybe a very great personality. No. Lord Śrī Kṛṣṇa is the Supreme Personality of Godhead. So at least theoretically, on the statement of Bhagavad-gītā or on the statement, assertion of Arjuna, the person who is trying to understand the Bhagavad-gītā, we should accept Śrī Kṛṣṇa as the Supreme Personality of Godhead, and then, with that submissive spirit... Unless one receives this Bhagavad-gītā in a submissive spirit and aural reception, it is very difficult to understand Bhagavad-gītā because it is a great mystery.
