There are above this Bhūrloka, Bhuvarloka, Janaloka, Tapoloka, Maharloka. There are so many planetary system. And down also, Tala, Atala, Vitala, Pātāla, Talātala, like that. If you want to go down, you can go down. If you want to go up, you can go. Ūrdhvaṁ gacchanti sattva . . . everything is there; you can do. Ordinary, anyone can understand that in the human society if you want to become high-court judge, you can become. And if you want to become a criminal in the prisonhouse, you can become. Everything is open. Not that government says that you become a criminal and he prefers somebody, "You become a high-court . . ." No. Everything is in your hand. If you like, you can become so. Similarly, if you like, you can go back to home, back to Godhead. That is perfection of life. And if you don't like, then remain here.
Therefore Kṛṣṇa says, aprāpya māṁ nivartante mṛtyu-saṁsāra-vartmani (BG 9.3). Kṛṣṇa has come to you to give you nice instruction how you can go back to home, back to Godhead. Back to home, back to Godhead. That is Kṛṣṇa's mission. Paritrāṇāya sādhūnāṁ vināśāya ca duṣkṛtam (BG 4.8). He comes Himself, Kṛṣṇa, and He comes as Caitanya Mahāprabhu, as devotee of Kṛṣṇa. Caitanya Mahāprabhu is Kṛṣṇa, but because people misunderstood that Kṛṣṇa is asking sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66) . . . these rascals thought that "It is too much. Why I shall surrender to Kṛṣṇa? I am also as good as Kṛṣṇa. Why shall I surrender?" That is our mentality. If somebody says, good man, that "You surrender. I shall give you good instruction," "Oh, why shall I surrender to you?" That is material life.
