Constant remembrance of Krishna through devotional service makes Him easily obtainable, unlike speculative knowledge.Listen — Srila Prabhupada Uvaca
Prabhupāda: ananya-cetāḥ satataṃ yo māṃ smarati nityaśaḥ tasyāhaṃ sulabhaḥ pārtha nitya-yuktasya yoginaḥ [Bg 8.14] [For one who remembers Me without deviation, I am easy to obtain, O son of Pṛthā, because of his constant engagement in devotional service.] Last day we have been discussing the..., how the impersonalist, they transfer themself in the spiritual kingdom. The yogīs and the jñānīs, they are generally impersonalist. So for them, the process—at the time of death, they vibrate the transcendental sound oṃ, oṃkāra, and by that way they transfer to the spiritual world. But they do not enter into the spiritual planet.
This point we have discussed. And the risk is that if we do not have any rest in the spiritual planet, if we remain in the outer space only, then there is risk of coming down again in this material world. The Bhāgavata confirms it: ye 'nye 'ravindākṣa vimukta-māninas 1 tvayy asta-bhāvād aviśuddha-buddhayaḥ āruhya kṛcchreṇa paraṃ padaṃ tataḥ patanty adho 'nādṛta-yuṣmad-aìghrayaḥ [SB 10.2.32] [[Someone may say that aside from devotees, who always seek shelter at the Lord's lotus feet, there are those who are not devotees but who have accepted different processes for attaining salvation. What happens to them? In answer to this question, Lord Brahmā and the other demigods said:] O lotus-eyed Lord, although nondevotees who accept severe austerities and penances to achieve the highest position may think themselves liberated, their intelligence is impure. They fall down from their position of imagined superiority because they have no regard for Your lotus feet.] It is said that "Persons who are interested of becoming liberated," ye 'nye 'ravindākṣa vimukta-māninaḥ, "simply by the concept of impersonal merging into the spiritual existence," so ye 'nye 'ravindākṣa, "they consider themself that they are liberated." That is also point of liberation, but the Bhāgavata says that "Although they consider themselves as liberated, the...," aviśuddha-buddhayaḥ. Aviśuddha means their knowledge is not very pure, not yet pure. Aviśuddha-buddhayaḥ. The result is āruhya kṛcchreṇa paraṃ padaṃ tataḥ: "They can rise up to the Supreme Absolute platform by their penances and austerities, meditation." That is right.
They can reach to that platform. Āruhya kṛcchreṇa. Āruhya kṛcchreṇa means "raising themselves, elevating themselves by severe penances to that platform," āruhya kṛcchreṇa paraṃ padam, the Supreme Absolute platform. But patanty adhaḥ: "They again fall down in this material world." Why? Anādṛta: "Because they have not taken seriously about Your personal feature." Anādṛta-yuṣmad-aìghrayaḥ: "Without worshiping Your lotus feet, the result is that they come down again in this material world." Just like however you may rise in this material space, five thousand feet or any, if you have no rest in any planet, then naturally you'll come down again, naturally, because you have no rest. So in the spiritual effulgence, if we do not have any rest, then we are sure to come back again down.
The reason is—that I have already explained—that our life... We, as living entities, we are part and parcel of the Supreme, sac-cid-ānanda. We want pleasure. So impersonal feature does not give us that pleasure which we want, which is our demand. That pleasure is available in the spiritual planets.
If you enter in any of the spiritual planets, then that spiritual happiness and exchange of pleasure you can attain. Therefore the Lord says, Kṛṣṇa, ananya-cetāḥ satataṃ yo māṃ smarati nityaśaḥ: "A person without any deviation..." Ananya-cetāḥ. Without any consideration of jñāna, yoga, or any other process, simply devotional process, simply surrendered process: "My Lord, I am Your eternal servant. Please give me Your service.
Let me engage. Let me be engaged in Your service." This is called ananya-cetāḥ. Ananya-cetāḥ satatam. Satatam means always, twenty-four hours, cent percent, without any deviation. This is Kṛṣṇa consciousness.
If anyone is engaged in such Kṛṣṇa consciousness, twenty-four hours and cent percent, then yo māṃ smarati nityaśaḥ, always remembering... Suppose if you are engaged in some work, naturally you'll be thinking of that particular work. When you go to your office and work, oh, you have to think always of the office business. That is quite natural.
