CC Madhya 8.89
diṣṭyā yad āsīn mat-sneho
The fulfillment of human life is summarized in this verse from Śrīmad-Bhāgavatam (10.82.44). There are two important words in this verse: bhakti (devotional service) and amṛtatva (eternal life). The aim of human life is to attain the natural position of eternal life. This eternal life can be achieved only by devotional service.
