SB 10.10.42

tad gacchatam mat-paramau
nalakuvara sadanam
sañjato mayi bhavo vam
ipsitah paramo ’bhavah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
O Nalakuvara and Manigriva, now you may both return home. Since you desire to be always absorbed in My devotional service, your desire to develop love and affection for Me will be fulfilled, and now you will never fall from that platform.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The highest perfection of life is to come to the platform of devotional service and always engage in devotional activities. Understanding this, Nalakuvara and Manigriva desired to attain that platform, and the Supreme Personality of Godhead blessed them with the fulfillment of their transcendental desire.
