Suppose in next life I become some demigod like Lord Brahmā or the Moon or the Sun. They are all demigods. Or Vāyu, Varuṇa. The Vaiṣṇava says, "No, we don't want this." Because either you become Rockefeller or Ford in this life, and next life the king of moon planet or sun planet or in any way, up to the Brahmā planet, Brahmaloka, Lord Brahmā, Kṛṣṇa says, ābrahma-bhuvanāl lokāḥ punar āvartino 'rjuna (BG 8.16): "My dear Arjuna, by your endeavor, even you become promoted to the highest position of this material world, still, you have to die, and again—either come down or remain there—there will be change of body." Ābrahma-bhuvanāl lokāḥ punar āvartino 'rjuna (BG 8.16). "So why should you be implicated in these material activities? Try to come to Me, back to home, back to Godhead. Then you'll haven't got to return again in this material world. That is the highest perfection." So this is called brahma-jijñāsā. By inquiring about Brahman one can understand that "Even if I go to the topmost planet of this material world, the four principles of miseries—birth, death, old age and disease—there is."
When Brahmā, Lord Brahmā, was asked by Hiraṇyakaśipu to make him immortal . . . he was undergoing severe penances to become immortal. So Lord Brahmā immediately said, "I am not immortal. How can I give you the benediction of immortality? That is not possible." Then, indirectly . . . he was very cunning. Then he, indirectly, he thought that "If I get benediction like this, I'll automatically become immortal." What is that? "Now, no man can kill me." "All right, that's all right." "No demigod can kill me." "That's all right." But he forgot God. Because he is godless, he did not say, "Even God cannot kill me." That he forgot.
