Prabhupāda: You may think that you have become liberated, you have got the position of Nārāyaṇa . . . that is all false thinking, aviśuddha-buddhayaḥ. They have been addressed as aviśuddha, nonpurified, buddhayaḥ, intelligent. Not intelligent. Ye 'nye 'ravindākṣa vimukta-māninas tvayy asta-bhāvāt (SB 10.2.32). This is . . . why these things happen, one compares Nārāyaṇa with ordinary demigod or ordinary man? Because aviśuddha-buddhayaḥ, their intelligence is not purified. So āruhya kṛcchreṇa paraṁ padaṁ tataḥ (SB 10.2.32). Such person, by severe austerities and penances, may elevate oneself to the position of Brahman. Still, āruhya kṛcchreṇa param . . . paraṁ padam means brahma-pada. Āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanty adhaḥ. Again he falls down. Why? Anādṛta-yuṣmad-aṅghrayaḥ: "Because they neglected to worship Your lotus feet."
So unless one becomes devotee, there is no secure position in the spiritual world. One may . . . just like a very crude example: you may have very powerful sputnik. Just like these people are trying to go the moon with powerful . . . what is called, the machine?
Devotees: Rocket.
Prabhupāda: Rocket, yes. But then, going with great force, but āruhya kṛcchreṇa . . . similarly, one can rise up to the Brahman effulgence, but if there is no shelter . . . just like these people are going, but they don't get any shelter. But they come down again. Similarly, one, by severe austerities and penances, may go up to the Brahmaloka, but he has no position. He has no position. Because in the Brahmaloka or Vaikuṇṭhaloka, in the Paravyoma, the spiritual sky, there are spiritual planets. They are called Vaikuṇṭhaloka. Hundreds and millions there are. Very, very big, big planets than these material planets. So unless you get a shelter in one of the planets, then you again fall down.
