Therefore Arjuna says that "Kṛṣṇa, whatever You are speaking in the Bhagavad-gītā, I accept in toto." That is study of Bhagavad-gītā. I do not select, "Oh, this portion is nice. I accept." Ardha-kukkuṭī-nyāya: (Cc. Ādi-līlā 5.176) "The back portion is nice. It is giving, the hen, daily, one egg. It is very nice. And the mouth portion is expensive. Cut it." The fool does not know if you cut this portion, that portion will be stopped also. So these, all these ordinary commentator... Just like Gandhi. He wanted to prove his nonviolence some way or other from Bhagavad-gītā. How he can prove? This is the same thing, that he was finding out, "If there is something, simply cutting the head, if I can get egg?" That is not possible. That is not... If we have to accept Bhagavad-gītā just like Arjuna says, that sarvam etad ṛtaṁ manye yad vadasi keśava: (BG 10.14) "My dear Kṛṣṇa, Keśava, whatever You are saying, I accept in toto. And this is confirmed by such authorities like Devala, Vyāsa, Asita. It is not that because we are friends, I am accepting You, but I know it is confirmed by such great authorities like Nārada, Asita, Vyāsa."
So we have to follow. This is called anu. Anu means following. Therefore it is recommended by Nārada that samādhinā anusmara: "You try to understand the activities of the Supreme Personality of Godhead by samādhi, by trance, meditation, by following the instruction of me, or predecessors, like that." This is the way.
