So Bhagavad-gītā is not a new thing, a new adventure. And the person who spoke Bhagavad-gītā to the sun-god, does it mean that He left something to be commented by some . . . these mundane man to understand the meaning of the Bhagavad-gītā? Such a great personality, the Supreme Personality of Godhead, He told something which is to be understood by the interpretation of a mundane scholar? Do you think it is reasonable? No. Whatever He spoke, that is all right. And that is clear. There is no question of interpreting in a different way.
Just like here, "The Blessed Lord said: 'I instructed this imperishable science of yoga to the sun-god Vivasvān.' " What is difficulty there? Is there any word which you cannot understand? Is anyone here who cannot understand these lines? It is clear. "The Blessed Lord said, 'I instructed this imperishable science of yoga to the sun-god Vivasvān.' " Everyone can understand that Kṛṣṇa instructed this science of Bhagavad-gītā, or the yoga of Bhagavad-gītā, to the sun-god, whose name is Vivasvān. It is clear. How you can interpret?
Now the thing is, unless I think of Kṛṣṇa that, "He is an ordinary man. How He could say to the sun-god Vivasvān?" then the interpretation is required. But that sort of thinking is not bona fide, because if you want to study Bhagavad-gītā, you have to take the words of Bhagavad-gītā. The Blessed Lord . . . He is Lord. He can say.
The Lord is not like ordinary man that, "Because we cannot say to the sun-god, therefore Kṛṣṇa cannot say," that is our foolishness. Why should we calculate Kṛṣṇa's activity with my activities? Therefore all the commentaries who think Kṛṣṇa as ordinary man, they are null and void. Such commentaries should not be accepted.
We have explained in our introduction that all the commentaries in the market, they are simply presentation of the particular commentator's personal view. That is not Bhagavad-gītā. If you want to understand Bhagavad-gītā, then you should understand as they are said. You don't interpret in your own way.
Now, because there should be some doubt of the ordinary man that, "How Kṛṣṇa could say to the sun-god?" that is explained in the next verse. Because Arjuna was taking instruction from Kṛṣṇa, he knew Kṛṣṇa, what He is. Otherwise he would not have accepted Him as a spiritual master.
But because others would doubt, "This is fictitious that Kṛṣṇa said to the sun-god. How it is possible?" So you will find Arjuna said, "The sun-god Vivasvān is senior by birth to You. How am I to understand that in the beginning You instructed this science to him?"
Kṛṣṇa is taking our position, er, Arjuna. Persons who are thinking of Kṛṣṇa as ordinary person, so Arjuna is trying to clear that point, that Kṛṣṇa is not ordinary person; He is the Supreme Personality of Godhead. Therefore he has put this question, that "The sun-god Vivasvān is senior by birth to You."
Sun-god, Vivasvān, the sun planet, father of Manu . . . Manu's age we cannot calculate. About forty millions of years ago Manu was born, and his father, we do not know what is his age. So how it is possible, if Kṛṣṇa is ordinary man, He spoke to him? That is being cleared.
So what He answered? "The Blessed Lord said: 'Many, many births both you and I have passed. I can remember all of them, but you cannot." That is the difference between God and man. That is the difference between God and man. We cannot remember. Even we cannot remember what I did at this time yesterday. That is our . . . forgetfulness is our nature.
