 SB 4.24.79

gitam mayedam naradeva-nandanah
 parasya pumsah paramatmanah stavam
japanta ekagra-dhiyas tapo mahat
 caradhvam ante tata apsyathepsitam
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
My dear sons of the King, the prayers I have recited to you are meant for pleasing the Supreme Personality of Godhead, the Supersoul. I advise you to recite these prayers, which are as effective as great austerities. In this way, when you are mature, your life will be successful, and you will certainly achieve all your desired objectives without fail.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
If we persistently engage in devotional service, certainly all our desires will be fulfilled in due course of time.
 
Thus end the Bhaktivedanta purports of the Fourth Canto, Twenty-fourth Chapter, of the Srimad-Bhagavatam, entitled “Chanting the Song Sung by Lord Siva.”
