It is not possible. So what to speak of understanding God? You cannot understand even what is in your presence, the material world, and spiritual is beyond the sky. Paras tasmāt tu bhāvaḥ anyaḥ (BG 8.20). That is another sky. You have no estimation of this sky. Not only this, this sky; even in the material world, this is one universe. What sky we see, that is of one universe. But there are innumerable universes. That is material world. And beyond that, there is spiritual sky. Then the spiritual world begins. There are also planets, Vaikuṇṭha planets. And above these Vaikuṇṭha planets, there is Kṛṣṇaloka. That is Kṛṣṇa's abode. Cintāmaṇi-prakara-sadmasu kalpa-vṛkṣa-lakṣāvṛteṣu (Bs. 5.29).
So you cannot understand Kṛṣṇa, or God, or His abode by the speculative, ascending process. That is not possible. You have to inquire from. Therefore Parīkṣit Mahārāja inquired from Śukadeva Gosvāmī, "What is my duty now I am going to die?" He was cursed by a brāhmaṇa boy to die within seven days. Parīkṣit Mahārāja was quite competent to counteract the curse of the brāhmaṇa boy, but he decided that "I shall die." Because he thought that "I offended the boy's father by encircling a dead snake on the neck of the ṛṣi. So his son became angry that 'You have insulted my father. You die with this snake.' " So he accepted. So this, on the death point, he immediately left his kingdom, family, and everything, and went down to the river, bank of the river Ganges, and many... Because he was king, so many big, big men, even demigods, great saintly persons, they came to see Mahārāja Parīkṣit at his last stage of life, seven days. And so he asked, "What is my duty?" So he was a devotee, Parīkṣit Mahārāja. From his childhood, he was a devotee of Kṛṣṇa. So he inquired, "What is my duty to know about Kṛṣṇa?" And that is being welcomed by Śukadeva Gosvāmī, that "Your, to inquire about Kṛṣṇa, this question is very much welcome." Varīyān eṣa te praśnaḥ (SB 2.1.1). Praśna means question. "You have asked a question about Kṛṣṇa. It is very, very good." Why? Kṛto loka-hitaṁ nṛpa: "It is good for the all human society. Because you have inquired about Kṛṣṇa, you have inquired about Kṛṣṇa, and I'll have to reply. People will hear. It will be recorded. And people will be benefitted." Loka-hitam.
