Sri Isopanisad

The karmīs, or fruitive workers, can elevate themselves to the Svargaloka planets, which include the sun and the moon. Jñānīs and yogīs can attain still higher planets, such as Maharloka, Tapoloka and Brahmaloka, and when they become still more qualified through devotional service they can enter into the spiritual nature.

Sri Isopanisad 14, Purport:

The predominating Supreme Person residing within the spiritual nature is Lord Śrī Kṛṣṇa. As confirmed in the Bhagavad-gītā (8.22), He can be approached only by unalloyed devotional service and not by the processes of jñāna (philosophy), yoga (mysticism) or karma (fruitive work). The karmīs, or fruitive workers, can elevate themselves to the Svargaloka planets, which include the sun and the moon. Jñānīs and yogīs can attain still higher planets, such as Maharloka, Tapoloka and Brahmaloka, and when they become still more qualified through devotional service they can enter into the spiritual nature, either the illuminating cosmic atmosphere of the spiritual sky (Brahman) or the Vaikuṇṭha planets, according to their qualification. It is certain, however, that no one can enter into the spiritual Vaikuṇṭha planets without being trained in devotional service.

On the material planets, everyone from Brahmā down to the ant is trying to lord it over material nature, and this is the material disease. As long as this material disease continues, the living entity has to undergo the process of bodily change. Whether he takes the form of a man, demigod or animal, he ultimately has to endure an unmanifested condition during the two devastations—the devastation during the night of Brahmā and the devastation at the end of Brahmā's life. If we want to put an end to this process of repeated birth and death, as well as the concomitant factors of old age and disease, we must try to enter the spiritual planets, where we can live eternally in the association of Lord Kṛṣṇa or His plenary expansions, His Nārāyaṇa forms. Lord Kṛṣṇa or His plenary expansions dominate every one of these innumerable planets, a fact confirmed in the śruti mantras: eko vaśī sarva-gaḥ kṛṣṇa īḍyaḥ/ eko 'pi san bahudhā yo 'vabhāti. (Gopāla-tāpanī Upaniṣad 1.21)
