There is a similar statement by Indra, the King of heaven, in Śrīmad-Bhāgavatam, Sixth Canto, 18th Chapter, 52nd verse. There Indra addresses his mother in this manner: "My dear Mother (Aditi), persons who have given up all kinds of desire and are simply engaged in devotional service to the Lord know what is actually their self-interest. Such persons are actually serving their self-interests and are considered first-class experts in the matter of advancing to the perfectional stage of life."
In the Seventh Canto of the Bhāgavatam, 6th Chapter, 23rd verse, Mahārāj Prahlāda says: "My dear friends who are born into atheistic families, if you can please the Supreme Personality of Godhead, Kṛṣṇa, then there is nothing more rare in this world. In other words, if the Supreme Lord Kṛṣṇa is pleased with you, then any desire that you may have within the core of your heart can be fulfilled without any doubt. As such, what is the use of elevating yourself by the results of fruitive activities, which are automatically achieved in all events by the modes of material nature? And what is the use for you of spiritual emancipation or liberation from material bondage? If you are always engaged in chanting the glories of the Supreme Lord and always relishing the nectar of the lotus feet of the Lord, then there is no necessity for any of these." By this statement of Prahlāda Mahārāj it is clearly understood that one who takes pleasure in chanting and hearing the transcendental glories of the Lord has already surpassed all kinds of material benedictions, including the results of pious fruitive activities, sacrifices and even liberation from material bondage.
Similarly, in the same Seventh Canto, 8th Chapter, 39th verse, when the demigods are offering prayers to Lord Nṛsiṁha, Indra, the King of heaven, says, "O Supreme One, these demons talk of our share of participation in the performances of ritualistic sacrifices, but simply by Your appearance as Lord Nṛsiṁhadeva You have saved us from terrible fears. Actually, our shares in the sacrificial performances are due to You only, because You are the supreme enjoyer of all sacrifices. You are the supersoul of every living entity, and therefore You are the actual owner of everything. Long were our hearts always filled with fear of this demon, Hiraṇyakaśipu. But You are so kind towards us that, by killing him, You have removed that fear from within our hearts and have given us the chance to place Your Lordship within our hearts again. For persons who are engaged in the transcendental loving service of Your Lordship, all the opulences which were taken away from us by the demons are counted as nothing. Devotees do not care even for liberation, not to speak of these material opulences. Actually, we are not enjoyers of the fruits of sacrifices. Our only duty is to always be engaged in Your service, for You are the enjoyer of everything."
The purport of this statement by Indra is that, beginning from Brahmā down to the insignificant ant, no living entities are meant for enjoying the material opulences. They are simply meant for offering everything to the supreme proprietor, the Personality of Godhead. By doing so, they automatically enjoy the benefit. The example can be cited again of the different parts of the body collecting foodstuffs and cooking them so that ultimately a meal may be offered to the stomach. After it has gone to the stomach, all the parts of the body equally enjoy the benefit of the meal. So, similarly, everyone's duty is to satisfy the Supreme Lord, and then automatically everyone will become satisfied.
A similar verse is found in the Eighth Canto, 3rd Chapter, of Śrīmad-Bhāgavatam, verse 20. Gajendra says there, "My dear Lord, I have no experience in the transcendental bliss derived from Your devotional service, so therefore I have asked from You some favor. But I know that persons who are pure devotees and have, by serving the lotus feet of great souls, become freed from all material desires, are always merged in the ocean of transcendental bliss and, as such, are always satisfied simply by glorifying Your auspicious characteristics. For them there is nothing else to aspire to or pray for."
