Indeed, there is no higher possible gain for embodied souls forced to wander throughout the material world than the Supreme Lord’s saṅkīrtana movement, by which one can attain the supreme peace and free oneself from the cycle of repeated birth and death.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
न ह्यतः परमो लाभो देहिनां भ्राम्यतामिह । यतो विन्देत परमां शान्तिं नश्यति संसृतिः
na hyataḥ paramo lābho dehināṃ bhrāmyatāmiha | yato vindeta paramāṃ śāntiṃ naśyati saṃsṛtiḥ
