Prabhupada's lecture - Śrīmad-Bhāgavatam 1.8.33 - Māyāpura, October 13, 1974
So you can call the Supreme Lord Kṛṣṇa or something else. Just like Muhammadans, they say "Allah." Allah means "the Supreme Being." Allah akbar. And the Christian says "God is great." And we say paraṁ brahma paraṁ dhāma [Bg. 10.12], or Kṛṣṇa, all-attractive. But the aim is to understand Kṛṣṇa, that Kṛṣṇa personally appears so that your misgivings, misunderstandings may be mitigated immediately—"Here I am." The Kṛṣṇa consciousness movement is for this purpose, that "You religionists, you philosophers, you scientists, you speculators, you are all... theosophists, so many, you are searching after God, and here is God, Kṛṣṇa." But they are so unfortunate, they'll not accept it. "No, why shall I accept Kṛṣṇa as God?" Then why you shall not? That is our question. If you do not accept Kṛṣṇa as God, then you must know what is God. That, if I ask him, "Do you know what is God?" "That I do not know."
The same... Just like the scientist. He would propose that life is made by combination of chemicals, but when another scientist says, "Suppose I give you the chemicals. Can you produce life?" he will, the rascal will say, "That I cannot say." Similarly, they are rascals. We are presenting herewith, "Here is Kṛṣṇa. Take His address. Take His name. Take His father's name, mother's name, all identification, His activities, His glories, everything." Kṛṣṇa proves that He's the Supreme Personality of Godhead:
aiśvaryasya samagrasya
vīryasya yaśasaḥ śriyaḥ
jñāna-vairāgyayoś caiva
ṣaṇṇāṁ bhaga itiṅganā
(Viṣṇu Purāṇa 6.5.47)
Bhagavān. Bhagavān means the proprietor of all wealth, aiśvarya, samagrasya. Not any limited amount, but samagra, everything. Kṛṣṇa says that. Bhoktāraṁ yajña..., sarva-loka-maheśvaram: [Bg. 5.29] "I am the proprietor of all the planets." Kṛṣṇa says that. So you check Him, that "How He is the proprietor of all the planets?" Therefore He showed Viśvarūpa, the universal form, how everything is within Him.
Everything is there. Arjuna wanted, requested Kṛṣṇa, that "How I can understand that You are the proprietor, You are the everything in the universe?" So He showed His universal form. Kṛṣṇa showed in every way to fulfill the proper definition of God, aiśvaryasya samagrasya, proprietor of everything, and vīryasya, the powerful. Nobody could kill Kṛṣṇa, but He killed so many demons, big, big demons. Therefore He's powerful. And His reputation? Still continuing, Kṛṣṇa. We are selling Kṛṣṇa book like anything. Why people are interested with Kṛṣṇa? Because He is reputed. People are seeing. The Kṛṣṇa consciousness movement is going on all over the world. This is yaśaḥ.
