Bhagavad-gita As It Is

BG Chapters 13 - 18

There are many less intelligent persons who take Bhagavad-gītā to be a discussion of topics between two friends on a battlefield. But such a book cannot be scripture.

BG 18.78, Purport: There are many less intelligent persons who take Bhagavad-gītā to be a discussion of topics between two friends on a battlefield. But such a book cannot be scripture. Some may protest that Kṛṣṇa incited Arjuna to fight, which is immoral, but the reality of the situation is clearly stated: Bhagavad-gītā is the supreme instruction in morality. The supreme instruction of morality is stated in the Ninth Chapter, in the thirty-fourth verse: man-manā bhava mad-bhaktaḥ. One must become a devotee of Kṛṣṇa, and the essence of all religion is to surrender unto Kṛṣṇa (sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja). The instructions of Bhagavad-gītā constitute the supreme process of religion and of morality. All other processes may be purifying and may lead to this process, but the last instruction of the Gītā is the last word in all morality and religion: surrender unto Kṛṣṇa. This is the verdict of the Eighteenth Chapter.
