Vivasvataḥ means the sun-god. "Oh, sun-god? Oh, sun planet was created some hundreds of millions of years before and You say that You said to sun-god? How it is possible because You are born not even hundred years completed?" Katham etad vijānīyāṁ tvam ādau proktavān iti: "Then how I am to understand it that You spoke formerly to sun-god?" It is, here... It is very intelligent question. It is very intelligent question. Now, what Kṛṣṇa answers? Śrī-bhagavān uvāca. Now, particularly said that, bhagavān uvāca: "The Personality of Godhead says." What does He say?
- bahūni me vyatītāni
- janmāni tava cārjuna
- tāny ahaṁ veda sarvāṇi
- na tvaṁ vettha parantapa
Now, the... (aside:) Yes, come on.
Kṛṣṇa says, "My dear Arjuna, yes, your question is very intelligent question that you are asking Me how it is possible that forty millions of years before I spoke this science of Bhagavad-gītā to the sun-god. Yes. But you, you should know it that bahūni me vyatītāni janmāni tava cārjuna, You and Myself... Although I am God, I take incarnation many, many times. And you are a living entity; you are also taking your birth repeatedly so many times. So we have passed already. The difference between you and Me is this, that tāni veda, tāny ahaṁ veda sarvāṇi, I, I remember what I did in the past, long, long years before, but you cannot remember." That is the difference between God and man, or God and living entity.
