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 pitṟn 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. There are different status of planets. So Devaloka, they are known just like that. The Bhagavad-gītā gives a very simple formula that you can go to the higher planets, Devaloka. Yānti deva-vratā devān. Yānti deva-vratā devān. Deva-vratā, if we practice the process of worshiping the particular demigod, then we can go to that particular planet also. We can go to the sun planet even, we can go to the moon planet, we can go to the heavenly planet, but Bhagavad-gītā does not advise us to go to any one of these planets in the material world because even we go to the Brahmaloka, the highest planet, which is calculated by the modern scientist that we can reach the highest planet by traveling with sputniks for 40,000 years. Now it is not possible to live 40,000 years and reach the highest planet of this material universe. But if one devotes his life in the worshipment of the particular demigod he can approach the particular planet, as it is stated in the Bhagavad-gītā: yānti deva-vratā devān pitṟn yānti pitṛ-vratāḥ (BG 9.25). Similarly, there is Pitṛloka. Similarly, one who likes to approach the supreme planet, supreme planet... The supreme planet means the Kṛṣṇaloka. In the spiritual sky there are innumerable planets, sanātana planets, eternal planets, which are never destroyed, annihilated. But of all those spiritual planets there is one planet, the original planet, which is called Goloka Vṛndāvana. So these informations are there in the Bhagavad-gītā and we are given the opportunity for leaving this material world and get our eternal life in the eternal kingdom. Now in the 15th Chapter of the Bhagavad-gītā, the real picture of this material world is given. It is said there that
- ūrdhva-mūlam adhaḥ-śākham
- aśvatthaṁ prāhur avyayam
- chandāṁsi yasya parṇāni
- yas taṁ veda sa veda-vit
- (BG 15.1)
