Śrīmad-Bhāgavatam
[Canto 4, Ch. 29]
teaching everyone to think always of Kṛṣṇa by executing devotional service. In this way, at the end of life, one may be transferred to the association of Kṛṣṇa. This is technically called  nitya-līlā-praviṣṭa , entering into the planet Goloka Vṛndāvana.  Bhagavad-gītā  explains:
bhaktyā mām abhijānāti yāvān yaś cāsmi tattvataḥ tato māṁ tattvato jñātvā viśate tad-anantaram
“One can understand the Supreme Personality as He is only by devotional service. And when one is in full consciousness of the Supreme Lord by such devotion, he can enter into the kingdom of God.” (Bg. 18.55)
After the mind is completely absorbed in Kṛṣṇa consciousness, one can enter the planet known as Goloka Vṛndāvana. To enter the association of the Supreme Personality of Godhead, one has to understand Kṛṣṇa. The process of understanding Kṛṣṇa is devotional service.
After understanding Kṛṣṇa as He is, one can become eligible to enter Kṛṣṇaloka and associate with Him. The mind is the cause of such an exalted position. The mind can also get one a body like dogs and hogs. To absorb the mind always in Kṛṣṇa consciousness is therefore the greatest perfection of human life.
