So difficulty is as living entity, we want enjoyment. Because I am not only simply existence. I have got bliss. Sac-cid-ānanda. I am, I am composed of three spiritual existence. I am eternal, and I am full of knowledge, and I am full of bliss. So those who enter into that impersonal effulgence of the Supreme Lord, they can remain eternally and with full knowledge that "I am now mixed up. I am now homogeneous with the Brahman. Bas." But they cannot have that eternal bliss because that part is wanting. So the difficulty is that when he feels... Just like you, if you are confined in a room alone, you may go on, you may engage yourself in reading some particular book or in some particular thought, but still, you cannot remain alone for all the years and all the time. That is not possible. You'll find some association. You'll find some association, recreation. That is our nature. So similarly, if we merge into the impersonal effulgence of the Supreme Lord, then there is chance of falling down again in this material world. That is stated in the Śrīmad-Bhāgavatam.
- ye 'nye 'ravindākṣa vimukta-māninas
- tvayy asta-bhāvād aviśuddha-buddhayaḥ
- āruhya kṛcchreṇa paraṁ padaṁ tataḥ
- patanty adho 'nādṛta-yuṣmad-aṅghrayaḥ
- (SB 10.2.32)
Just like this sputnik man, the aeronautics, they go higher and higher, twenty-five thousand or thirty thousand or hundred thousand miles away. But if they cannot take rest in some planet, they'll fall down, at once fall down again. So the rest is required. In the impersonal form the rest is uncertain, uncertain. Therefore in the Bhāgavata says that āruhya kṛcchreṇa paraṁ padaṁ tataḥ (SB 10.2.32). Even after so much endeavor, if he gets into the spiritual world and remains in that impersonal form, the risk is that patanty adhaḥ: he comes down again into this material world. Why? Anādṛta-yuṣmad-aṅghrayaḥ, because he has neglected to serve in love and devotion the Supreme Lord.
In this... So, so long we are here, we have to practice to love Kṛṣṇa, the Supreme Lord. Then we can enter. This is the training. And if we are not trained up in that way, then, by impersonal endeavor, we can enter into the spiritual kingdom, but there is risk of falling down again. Because that alone, that loneliness, will create some disturbance, and he will try to have association. And because he has no association of the Supreme Lord, he will have to come back into this material world and associate with this material association. So better that we should know the nature of our constitutional position. Our constitutional position is that we want eternity, we want complete knowledge and we want pleasure also, pleasure. So if you are kept alone, you cannot have pleasure. Then you'll feel uncomfortable. And for want of pleasure, you'll accept any kind of pleasure: "All right, material pleasure." That's all. That is the risk.
Therefore this Kṛṣṇa, Kṛṣṇa consciousness, you'll have full pleasure, full pleasure, the same pleasure. Not the same pleasure. Just like here the highest pleasure of this world is sex life. That is also perverted, so diseased. So even in the spiritual world there is sex pleasure in Kṛṣṇa, but that's not... We should not think that this is something like this. No. But janmādy asya yataḥ (SB 1.1.1). Unless that sex life is there, it cannot be reflected here. It is simply perverted reflection. The actual life is there, in Kṛṣṇa. Kṛṣṇa is full of pleasure. So best thing is to train ourself, train ourself in this Kṛṣṇa consciousness, and then it will be possible in this life at the time of death to transfer ourself into the spiritual world and enter into the Kṛṣṇaloka, or the Kṛṣṇa planet, and enjoy with the association of Kṛṣṇa.
- cintāmaṇi-prakara-sadmasu kalpa-vṛkṣa-
- lakṣāvṛteṣu surabhīr abhipālayantam
- govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
- (Bs. 5.29)
This, these are the description of the Kṛṣṇaloka. Cintāmaṇi-prakara-sadmasu: "The houses are made of touchstone." Touchstone. Perhaps you know touchstone. It's a... A small particle touchstone, if it is touched in the iron beam, it will at once becomes gold. Of course, I do not know if any one of you has seen this touchstone, but there is such a thing. So all the buildings are there of touchstone. Cintāmaṇi-prakara-sadmasu kalpa-vṛkṣa (Bs. 5.29). The trees are desire trees. Whatever you like, can get. Here from mango tree, you get mango, and apple tree from, you get apple. But there any tree, anything you like, you can have. These are the some, some of the description of the Kṛṣṇaloka.
So best thing is not to try for elevate, for elevating ourselves in either of these material planet. Because in any material planet you enter, the same principles of miserable life... We are accustomed. We have been acclimatized to birth, death. We don't care. The modern scientists, they are very much proud of their advancement, but they have no solution of these unpleasant things. They cannot make anything which will check death, or which will check disease, or which will check old age. That is not possible. You can, you can manufacture something which will accelerate death, but you cannot manufacture anything which will stop death. That is not in your power. So those who are intelligent enough, they are not concerned with these four things, janma-mṛtyu-jarā-vyādhi: (BG 13.9) birth, death and old age. They are concerned to have a spiritual life, complete, full of bliss and full of knowledge, and that is possible when you enter into the spiritual planets. That will be explained.
