If you want to go to the higher planetary system by pious activities, you can go there, yānti deva-vratā devān. You can go to the planet where Lord Brahmā lives or where Indra lives or Candra lives. The modern process, by taking a sputnik or jet, you can go to the moon planet. But that you can go. Whether you can go or not go, that is up to you. But you cannot stay there. That is not possible. If you want to stay there, then yānti deva-vratā devān. You have to prepare yourself by worshiping that particular deva or deity, demigod; then you will be admitted. Just like if you want to go to a foreign country you have to take the permission of the immigration department, visa, then you can go. If that law is there in this planet, why not for other planet? How you can go abruptly, by force? That is not possible. Yānti deva-vratā devān. You have to prepare yourself to go. You can go there. But after this life, if you are sufficiently prepared to enter that particular type of planet, you can go there. Similarly, you can go to the planet where Kṛṣṇa lives. Mad-yājino 'pi yānti mām (BG 9.25).
So what is the difference between going to the higher planetary systems, heavenly planet, and going to the planet where Kṛṣṇa lives? The difference is, yad gatvā na nivartante tad dhāma paramaṁ mama (BG 15.6). If you go to the planet where Kṛṣṇa lives, then you haven't got to come back again. Otherwise, in other planets, in the heavenly planets, kṣīṇe puṇye punar martya-lokaṁ viśanti. You can live there, just like you can live in a foreign country so long your visa continues. Simply . . . similarly, you can go to the higher, heavenly planets, but you can live there up to the point of visa, puṇya. By pious activities you can go to the higher planetary system, but impious activities, you go to the lower planetary. Adho gacchanti tāmasāḥ. Adho gacchanti tāmasāḥ, jaghanya-guṇa-vṛtti-sthā, ūrdhvaṁ gacchanti sattva-sthā (BG 14.18). So even if you go ūrdhva-lokam, brahma-lokam—ā-brahma-bhuvanāl lokāḥ punar āvartinao 'rjuna (BG 8.16)—you have to come back again. But, yad gatvā na nivartante, tad dhāma paramaṁ mama (BG 15.6). If you go to that planet, yad gatvā na nivartante, one does not require to come back again. "That is My real abode." Tad dhāma paramam. Every dhāma is Kṛṣṇa's, but that is the parama dhāma, supreme dhāma. Just like the king: the kingdom belongs to the king, but still he has got a special royal house, palace. Similarly, Kṛṣṇa is the proprietor of all planets, sarva-loka-maheśvaram (BG 5.29), but still He has got His own planet. That is called Gokula Vṛndāvana.
So this Kṛṣṇa consciousness movement is a movement to educate people how he can go back to home, back to Godhead, Kṛṣṇa. So our request is that you take advantage of this movement. Don't be fully simply absorbed in the activities of animal life—eating, sleeping, mating and defending. This is also required, but under regulation. Eating is not prohibited in Kṛṣṇa consciousness movement, but eating is regulated. Don't eat anything without Kṛṣṇa's prasādam. Oh, Kṛṣṇa prasādam, there are so many varieties nice foodstuff. Be satisfied taking Kṛṣṇa's prasādam, so your eating problem will be solved and you will advance in Kṛṣṇa consciousness to go back to home, back to Godhead. So this Kṛṣṇa consciousness movement is very important movement for the human society, and this is not a utopianan thing. It is authorized. For every action of Kṛṣṇa consciousness movement there is support from Veda, Vedic literature. Just like whenever we speak something we immediately give evidence from the Bhagavad-gītā. It is not that something, "In my opinion it is . . ." No. We have no opinion. We don't give our opinion. We present Bhagavad-gītā as it is, that's all. As Kṛṣṇa says, we say the same thing. We have no difficulty. Kṛṣṇa says, mattaḥ parataraṁ nānyat, kiñcid asti dhanañjaya (BG 7.7). "There is no more superior truth than Kṛṣṇa," Kṛṣṇa says. We accept that. We preach that, that Kṛṣṇa is the Supreme Personality of Godhead. Kṛṣṇas tu bhagavān svayam (SB 1.3.28). If you are searching after God, that is your duty. Athāto brahma jijñāsā. That is your human life's business, to search out the truth, Absolute Truth. Then that is Kṛṣṇa, that is Kṛṣṇa.
In the Vedānta-sūtra it is indirectly said: "The Absolute Truth is janmādy asya yataḥ (SB 1.1.1), from whom everything is generated." That is Absolute Truth. That answer is given in the Bhagavad-gītā, aham sarvasya prabhavaḥ mattaḥ sarvaṁ pravartate (BG 10.8): "I am the origin of everything." Aham ādir hi devānām (BG 10.2). Somebody may say the demigods like Lord Brahmā, Śiva, they are the beginning demigod. But Kṛṣṇa says, aham ādir hi devānām: "They, all the demigods, but their beginning, they are also coming from Me." Sarvasya prabhavaḥ mattaḥ sarvaṁ pravartate. These things are there. So we are teaching that. It is not difficult. We are not manufacturing anything by fertile brain. Everything is there in the Bhagavad-gītā, and we are presenting Bhagavad-gītā as it is, preaching the Bhagavad-gītā as it is. The Bhāgavata is also further explanation of Bhagavad-gītā, Vedānta-sūtra explanation.
