Śrimad-Bhāgavatam
[Canto 7, Ch. 7]
puṇya-jito lokaḥ kṣīyata.  As the material positions we acquire here by hard work are vanquished in due course of time, one's residence in the heavenly planets is also eventually vanquished. According to one's activities of piety in different degrees, one obtains different standards of life, but none of them are permanent, and therefore they are all impure. Consequently, one should not endeavor to be promoted to the higher planetary systems, only to return to this earth or descend still lower to the hellish planets. To stop this cycle of going up and coming down, one must take to Kṛṣṇa consciousness. Śrī Caitanya Mahāprabhu therefore said:
brahmāṇḍa bhramite kona bhāgavān jīva guru-kṛṣṇa-prasāde pāya bhakti-latā-bīja  (Cc. Madhya 19.151)
The living entity is rotating in the cycle of birth and death, going sometimes to the higher planets and sometimes to the lower planets, but that is not the solution to the problems of life. But if by the grace of Kṛṣṇa one is fortunate enough to meet a  guru , a representative of Kṛṣṇa, one gets the clue to returning home, back to Godhead, having achieved self-realization. This is what is actually desirable.  Bhajatātma-labdhaye : one must take to Kṛṣṇa consciousness for self-realization.
