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."
In the Ninth Canto of the Bhāgavatam, 4th Chapter, 49th verse, the lord of Vaikuṇṭha replies to Durvāsā Muni thusly: "My pure devotees are always satisfied being engaged in devotional service, and therefore they do not aspire even after the five liberated stages, which are 1) to be one with Me, 2) to achieve residence on My planet, 3) to have My opulences, 4) to possess bodily features similar to Mine and 5) to gain personal association with Me. So, when they are not interested even in these liberated positions, you can know how little they care for material opulences or material liberation."
There is a similar prayer by the nāgapatnī (wives of the Kāliya serpent), in the Tenth Canto of Śrīmad-Bhāgavatam, 16th Chapter, verse 33. The nāgapatnī say there, "My dear Lord, the dust of Your lotus feet is very wonderful. Any person who is fortunate enough to achieve this dust does not care for heavenly planets, lordship over all the planetary systems, the mystic perfections of yoga or even liberation from material existence. In other words, anyone who adores the dust of Your lotus feet does not care a fig for all other perfectional stages."
There is a similar statement in the Tenth Canto, 87th Chapter, 17th verse, when the Śrutis, the Vedas personified, prayed to the Lord as follows: "My dear Lord, it is very difficult to understand spiritual knowledge. Your appearance here just as You are, is to explain to us this most difficult subject of knowledge of the spirit. As such, Your devotees who have left their domestic comforts to associate with the liberated ācāryas (teachers) are now fully merged in the devotional service of Your Lordship, and thus they do not care for any so-called liberation."
