Now, here also it is stated, sa kāleneha mahatā yogo naṣṭaḥ parantapa: "My dear Arjuna, oh, you are the great hero. Now, that Bhagavad-gītā, the instruction which I imparted to the sun-god, was coming by disciplic succession. Now it is lost." Now, we have to note down this point. Why it is lost? Why it is lost? Do you think that there was no learned man during that time? During Kṛṣṇa's time? Oh, there were many learned sages. Not only one, two, there were dozens of learned sages. But still, the Lord said, Kṛṣṇa said, that "They... That knowledge which I exactly imparted to sun-god is now lost." How it is lost? There were many scholars, and still, how it is lost? The lost means that the purport of Bhagavad-gītā is lost.
Because scholars they can interpret in their own way about Bhagavad-gītā, but that is not Bhagavad-gītā. That is not Bhagavad-gītā. That is the purport which Kṛṣṇa wants to stress. So any student of Bhagavad-gītā must note it, that Bhagavad-gītā commented by a person—he may be very scholar in the material sense, but that scholarship will not help to comment on the Bhagavad-gītā. The Bhagavad-gītā, to understand Bhagavad-gītā, we have to accept this disciplic succession principle as Lord Kṛṣṇa says to Arjuna, that "It is coming down by disciplic succession." We have to take that spirit. And without taking that spirit, simply by our erudite scholarship, if we want to understand Bhagavad-gītā, that is a misunderstanding. That is the purpose He has said.
