So the karmīs, karma-kāṇḍīya, they are trying to be elevated to the heavenly planet, higher planetary system. That is not very good idea. You can go to the higher planetary system by your pious activities. First of all the modern age, the people are so much impious, sinful, that is not also possible. They may go down. Jaghanya-guṇa-vṛtti-sthā adho gacchanti tāmasāḥ. They are covered with ignorance. The ignorance is wine, women, and meat-eating. So they are going down. There is no possibility of going higher planetary system, not possible. Who will go to the higher planetary system? Ūrdhvaṁ gacchanti sattva-sthāḥ (BG 14.18). Ūrdhvam means higher. Only those who are pious, they can be elevated. So even if you are pious, still you have to come back again. This is the process. So sarva-gataḥ. Sarva-gataḥ means a soul is free to go anywhere, anywhere. Full freedom, as he wants. That is also explained in the Bhagavad-gītā:
- yānti deva-vratā devān
- pitṟn yānti pitṛ-vratāḥ
- bhūtāni yānti bhūtejyā
- yānti mad-yājino 'pi mām
- (BG 9.25)
As you like. It is up to you. Make your selection where you want to be. You have, somehow or other, you have come here. That's all right. But Kṛṣṇa gives you chance to be elevated to any planetary system you like. Ultimately, if you want to go back to home, back to Godhead, that is also given, everything. Mad-yājino 'pi yānti mām. So if you want to go to the moon planet, there is no need of the sputnik. There is a process so that after this body you become elevated to the moon planet. Why should you make research for, and futile research, going to the moon? You just prepare yourself. There are different processes. If you want to go to the moon planet, you can go. If you want to go to the heavenly planet, you can go. Similarly, if you want to go to the planet where Kṛṣṇa is, you can go. So sane man, intelligent man, should consider that "If I have to prepare myself for going, for being elevated to the higher planetary system, but we have to come back again, kṣīṇe puṇye martya-loka, why not endeavor for going back to Kṛṣṇaloka?" That is intelligence. But there are big, big yogis, they elevate themselves to the higher planetary system. They... Before going to the spiritual world, they want to see how the higher planetary system are working. Just like the visitors, tourists. They are going somewhere, and drop, by journey, somewhere to see. But you should not make such ambition. You should endeavor directly going back to home, back to Godhead, Kṛṣṇa. That should be your endeavor. Yes. Mad-yājino 'pi yānti mam (BG 9.25).
