God remembers all eternities while souls forget; both are eternal, yet Krishna is supreme and individuals subordinate.Listen — Srila Prabhupada Uvaca
] Prabhupāda: [leads kīrtana] [prema-dhvani] [devotees offer obeisances] [21:38] bhagavān uvāca bahūni me vyatītāni janmāni tava cārjuna tāny ahaṁ veda sarvāṇi na tvaṁ vettha parantapa [Bg. 4.5] [The Blessed Lord said: Many, many births both you and I have passed. I can remember all of them, but you cannot, O subduer of the enemy!] Now Kṛṣṇa is explaining to Arjuna the difference between a living entity and the Supreme Personality of Godhead. It is very distinct here that "Both you and Me had many, many, many other appearances and disappearances." "Birth and death," that is ordinary word. Actually, the word is "appearance and disappearance." Just like the sun. The sun sets and sun rises.
This is our calculation. The sun is there always, twenty-four hours, but to our limited understanding, because we cannot see... Now just this is sun-setting time. After setting of the sun, the people on this part of the world, they will not see the sun.
That does not mean that sun is not there. Sun is there, but this part of the world cannot see it, and that we say sunset. Similarly, if this is possible for a material object... Sun is nothing but a material object, lump of material matter, very powerful, predominantly fiery. That's all.
Everything in the material world, they're made of five elements: ether, air, and fire, water and earth. So in somewhere the earth is predominant, somewhere the air is predominant, somewhere the fire is predominant. So there are innumerable planets, and the sun is one of them. So this is also material object. If it is possible for the material object to disappear and appear within our limited senses, what to speak of God and His devotees.
So God does not mean that because He is not visible to our imperfect senses, therefore God has no existence. This is foolishness. God is existent. But one who has got eyes to see... What is that eye?
Just like a small child. If I say to the small child, so "Sun is there in the sky," and the child will say, "Show me where is the sun." And if somebody says, "Yes, come on, I shall show you sun. Come on the roof. I have got a torch-light..." As it is not possible to show the sun at night, although the child is insisting, similarly, the so-called scientists who are claiming that there is no God, they're just like the child. You have to understand.
Just like a man who is advanced in knowledge, he knows that sun is there. Although I cannot see at night, but sun is there. He's convinced. Similarly, those who are advanced in spiritual knowledge, they can see God in every moment premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva hṛdayeṣu vilokayanti [Bs. 5.38] [I worship Govinda, the primeval Lord, who is Śyāmasundara, Kṛṣṇa Himself with inconceivable innumerable attributes, whom the pure devotees see in their heart of hearts with the eye of devotion tinged with the salve of love.] And what is that scientific knowledge?
