Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O best of kings, one who is faithful, who is always hearing the glories of the Supreme Personality of Godhead, who is always engaged in the culture of Krsna consciousness and in hearing of the Lord’s activities, very soon becomes eligible to see the Supreme Personality of Godhead face to face.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Constant engagement in the transcendental loving service of Vasudeva means constantly hearing the glories of the Lord. The principles of bhakti-yoga — sravanam kirtanam visnoh smaranam pada-sevanam/ arcanam vandanam dasyam sakhyam atma-nivedanam — are the only means by which perfection can be attained. Simply by hearing of the glories of the Lord, one is elevated to the transcendental position.
