Jñānam, the jñānīs, they want to know. Just like Brahmā wanted to test whether Kṛṣṇa is God or not. Indra wanted to test whether... The inhabitants of Vṛndāvana, they never did it. They think, "Kṛṣṇa is our very intimate friend, my beloved son, my lover, my master." Everyone's concentrated love for Kṛṣṇa in different mellows.
That's all. Even when Kṛṣṇa played wonderful thing, so they simply thought, "Oh, He might be a demigod." You see. So they never tried to analyze Kṛṣṇa, but their love for Kṛṣṇa, there is no comparison. So that is wanted. Jñāna-karmādy-anāvṛtam (CC Madhya 19.167). "Whether Kṛṣṇa is God or not, let me test." You can test, but pure love means whatever Kṛṣṇa may be, He is my lovable object: mat-prāṇa-nāthas tu sa eva nāparaḥ. We have no other business than to love Kṛṣṇa, whatever He may be. He may be God or He may be whatever He may be. That is called anyābhilāṣitā-śūnyaṁ jñāna-karmādy-anāvṛtam (Brs. 1.1.11). Then what is the business? If everything is śūnyam... Śūnyam means zero. No, we are not zero. We are positive. What is that? Ānukūlyena kṛṣṇānuśīlanam (CC Madhya 19.167). Simply cultivate Kṛṣṇa consciousness favorably: "How I can become a lover of Kṛṣṇa?" That is wanted. Ānukūlyena kṛṣṇānuśīlanaṁ bhaktir uttamā. This is first-class devotion service. Of course, we should know Kṛṣṇa; otherwise, it may be we may neglect Him.
Just like we are trying to explain what is Deity. But if one has got unflinching love for the Deity, he doesn't require to understand the Deity through the śāstra. Spontaneous love.
