"When such a person reaches the perfectional stage, he returns home, back to Krsna, in his pure spiritual identity"

CC Madhya-lila

A person engaged in devotional service may accept any one of these transcendental relationships, which are known as mellows. When such a person reaches the perfectional stage, he returns home, back to Kṛṣṇa, in his pure spiritual identity.

CC Madhya 9.131, Translation and Purport:

"One who worships the Lord by following in the footsteps of the inhabitants of Vrajabhūmi attains Him in the transcendental planet of Vraja, where He is known as the son of Mahārāja Nanda."

The inhabitants of Vrajabhūmi, or Goloka Vṛndāvana, know Kṛṣṇa as the son of Mahārāja Nanda. They do not accept Him as the Supreme Personality of Godhead, as people in general do. The Lord is the supreme maintainer of everyone and the chief personality among all personalities. In Vrajabhūmi Kṛṣṇa is certainly the central point of love, but no one knows Him there as the Supreme Personality of Godhead. Rather, a person may know Him as a friend, son, lover or master. In any case, the center is Kṛṣṇa. The inhabitants of Vrajabhūmi are related to the Lord in servitude, friendship, parental love and conjugal love. A person engaged in devotional service may accept any one of these transcendental relationships, which are known as mellows. When such a person reaches the perfectional stage, he returns home, back to Kṛṣṇa, in his pure spiritual identity.
