Srimad Bhagavatam Canto 08, Chapter 12, Text 46

SB 8.12.46

etan muhuh kirtayato ’nusrnvato
 na risyate jatu samudyamah kvacit
yad uttamasloka-gunanuvarnanam
 samasta-samsara-parisramapaham
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The endeavor of one who constantly hears or describes this narration of the churning of the Ocean of Milk will never be fruitless. Indeed, chanting the glories of the Supreme Personality of Godhead is the only means to annihilate all sufferings in this material world.
