So here it is mentioned, trai-vidyā soma-pāḥ pūta-pāpāḥ. They, after preparing themselves to be transferred in other planets, they become free from all sinful reaction. The higher planet, as you go, you have to become free from sinful action. The lower grade life and higher grade life in this material world means those who are proportionately less sinful, they are promoted in higher planets. You cannot be free from sinful reaction in this material world. There will be some portion, some percentage. So the higher grade life and lower grade life means those who are proportionately greater sinful, they have got lower grade life, and those who have got greater pious life, they get higher grade life in higher planets, in Brahmaloka, Janaloka, Tapoloka. Tapoloka means those who have performed here severe penances, and they are transferred there in Tapoloka. In Tapoloka, when there is destruction, annihilation of this material world, in the Tapoloka there is no destruction. They get information, "Now annihilation has begun." There is a great fire, and they still feel that heat, and at that time they transfer themselves to the spiritual sky. That mention we have got. So yajñair iṣṭvā svargatiṁ prārthayante.
So these materialists... Anyone, even if you go to the higher planets, still, you are materialist. Even you go to the highest planet, Brahmaloka, where the duration of life you cannot calculate, still there is death. The material pangs, birth, death, old age and disease, there is. So in the Bhagavad-gītā we get all this information, where other planets are, what is the condition. Simply we have to know it from this book. Similarly, we have got information of the supreme planet Kṛṣṇaloka, or the planet of Kṛṣṇa, where you can go. The Lord says, yad gatvā na nivartante tad dhāma paramaṁ mama: (BG 15.6) "The planet where going you have no more to come back." Now, these planets, these material planets, as it is mentioned here, surendra-loka... Surendra means highly qualified demigods, their planets. Surendra-lokam aśnanti. Aśnanti means they enjoy. And what do they enjoy? Divyān divi deva-bhogān. They enjoy godly comforts, deva-bhogān.
