That abode of Lord, there are innumerable planets also in that brahma-jyoti. Just like we have got innumerable planets floating on the sun rays, similarly, in the brahma-jyoti, which is emanating from the abode of the Supreme Lord, Kṛṣṇaloka, Goloka, ānanda-cinmaya-rasa-pratibhāvitābhis (Bs 5.37), all those planets are spiritual planets. They are ānanda-cinmaya: they are not material planets. So the Lord says:
- na tad bhāsayate sūryo
- na śaśāṅko na pāvakaḥ
- yad gatvā na nivartante
- tad dhāma paramaṁ mama
- (BG 15.6)
Now, anyone who can approach that spiritual sky will not be required to come back again in this material sky. So long we are in the material sky, what to speak of approaching the moon planet . . .
The moon planet, of course, is the nearest planet, but even we approach the highest planet, which is called Brahmaloka, there also we have the same miseries of material life, I mean to say, the miseries of birth, death, old age and diseases. No planets in the material universe is free from the four principles of material existence. The Lord therefore says in the Bhagavad-gītā, ābrahma-bhuvanāl lokāḥ punar āvartino 'rjuna (BG 8.16).
The living entities are traveling from one planet to another. It is not that we can simply go to other planets by the mechanical arrangement of the sputnik. Anyone who desires to go to other planet, there is process. Yānti deva-vratā devān pitṝn yānti pitṛ-vratāḥ (BG 9.25).
If anyone wants to go to any other planet, say moon planet, we need not try to go by the sputnik. The Bhagavad-gītā instructs us, yānti deva-vratā devān. These moon planets or sun planets or the planets above this Bhūloka, they are called Svargaloka. Svargaloka. Bhūloka, Bhuvarloka, Svargaloka, they are different status of planets. So . . . devaloka. They are known just like that.
