Kṛṣṇa, the Supreme Personality of Godhead, personally appeared and left His instructions for the benefit of all human society, but fools and rascals unfortunately think of Him as an ordinary human being and twist the instructions of Bhagavad-gītā for the satisfaction of their senses. Practically everyone commenting on Bhagavad-gītā interprets it for sense gratification. It has become especially fashionable for modern scholars and politicians to interpret Bhagavad-gītā as if it were something fictitious, and by their wrong interpretations they are spoiling their own careers and the careers of others. The Kṛṣṇa consciousness movement, however, is fighting against this principle of regarding Kṛṣṇa as a fictitious person and of accepting that there was no Battle of Kurukṣetra, that everything is symbolic, and that nothing in Bhagavad-gītā is true. In any case, if one truly wants to be successful, one can do so by reading the text of Bhagavad-gītā as it is. Śrī Caitanya Mahāprabhu especially stressed the instructions of Bhagavad-gītā: yāre dekha, tāre kaha ‘kṛṣṇa’-upadeśa. If one wants to achieve the highest success in life, one must accept Bhagavad-gītā as spoken by the Supreme Lord. By accepting Bhagavad-gītā in this way, all of human society can become perfect and happy.
