The story behind this verse is that the two sons of Kuvera (the treasurer of the demigods) were puffed up on account of the opulence of their father, and so once on a heavenly planet they were enjoying themselves in a lake with some naked damsels of heaven. At that time the great saint Nārada Muni was passing on the road and was sorry to see the behavior of the sons of Kuvera. Seeing Nārada passing by, the damsels of heaven covered their bodies with cloth, but the two sons, being drunkards, did not have this decency. Nārada became angry with their behavior and cursed them thus: "You have no sense, so it is better if you become trees instead of the sons of Kuvera." Upon hearing this, the boys came to their senses and begged Nārada to be pardoned for their offenses. Nārada then said, "Yes, you shall become trees, arjuna trees, and you will stand in the courtyard of Nanda Mahārāja. But Kṛṣṇa Himself will appear in time as the foster son of Nanda, and He will deliver you." In other words, the curse of Nārada was a benediction to the sons of Kuvera because indirectly it was foretold that they would be able to receive the favor of Lord Kṛṣṇa. After that, Kuvera's two sons stood as two big arjuna trees in the courtyard of Nanda Mahārāja until Lord Dāmodara, in order to fulfill the desire of Nārada, dragged the grinding mortar to which He was tied and struck the two trees, violently causing them to fall down. From out of these fallen trees came Nalakūvara and Maṇigrīva, who had by then become great devotees of the Lord.
There is a passage in the Hayaśīrṣa Pañcarātra which states, "My dear Lord, O Supreme Personality of Godhead, I do not want any resultant benediction from my religious life, nor do I want any economic development, nor do I want to enjoy sense gratification, nor liberation. I simply pray to be an eternal servant at Your lotus feet. Kindly oblige me and give me this benediction."
