So in this life you have to prepare yourself. Then you can go to the higher planetary system.
- ūrdhvaṁ gacchanti sattva-sthā
- madhye tiṣṭhanti rājasāḥ
- jaghanya-guṇa-vṛtti-sthā
- adho gacchanti tāmasāḥ
- (BG 14.18)
You can go, sarva-ga. Every living entity can go wherever he likes but he must fulfill the condition because we are in the conditional state. The material world means we are conditioned. So in order to be eligible to go to the higher planetary system like moon planet and others, we must be efficient to prepare ourself. So that preparation means the more you become situated in the sattva-guṇa, śaucam. Satyaṁ śaucam, the brahminical qualification, ārjavam āstikyam, jñānaṁ vijñānam āstikyaṁ brahma-karma svabhāva-jam (BG 18.42). Unless you acquire the qualities of sattva-guṇa, you cannot go even in the higher planetary system, what to speak of going beyond the universe. Beyond the universe, beyond this, there are Vaikuṇṭhaloka, or the Brahmaloka, brahma-jyotir. Then topmost is the Goloka Vṛndāvana. But you can go there. Kṛṣṇa says, mad-yājino 'pi yānti mām (BG 9.25). If you prepare in this life, then you can go there. There is no impediment. Simply you have to be purified. This bhakti-mārga is the process of purification.

- (CC Madhya 19.170)
If we want to go to Vaikuṇṭha planet or Goloka Vṛndāvana planet, beyond this material sky... That is... There is another sky. Paras tasmāt tu bhāvaḥ anyaḥ avyakto 'vyaktāt sanātanaḥ (BG 8.20). These informations are there in the Bhagavad-gītā. There is another sky which is called paravyoma. That is spiritual sky. That spiritual sky is eternal. When everything is annihilated within this material sky, that remains eternally. That is called sanātana-dhāma. So sanātana-jīva, sanātana. Mamaivāṁśo jīva-loke sanātanaḥ (BG 15.7). It is stated there. So jīva is sanātana. Na hanyate hanyamāne śarīre (BG 2.20). And Kṛṣṇa is also sanātana. In the Eleventh Chapter Kṛṣṇa is addressed, sanātana. And here there is another sky which is called sanātana. Avyaktaḥ avyaktāt sanātanaḥ. So this sanātana-dhāma and sanātana association... Kṛṣṇa is sanātana, living entity is sanātana, and there is a sanātana-dhāma.
