A pure devotee accepts the transcendental loving service of the Lord but rejects all kinds of liberation for his personal sense gratification. This is stated by Lord Kapila in Śrīmad-Bhāgavatam (3.29.11-14), in His explanation of the nature of pure devotional service. As soon as a pure devotee hears the glories and transcendental qualities of the Supreme Personality of Godhead, who is seated in everyone's heart, his mind at once flows toward the Lord, just as the waters of the Ganges flow down toward the sea. Such spontaneous attraction of the devotee's mind to the service of the Supreme Personality of Godhead signifies pure devotional service.
Devotional service is pure when one engages in the service of the Supreme Lord without any selfish motive and without being hampered by any material impediment. The pure devotee does not desire to live on the same planet as the Supreme Lord, nor does he desire the same opulence as the Lord, nor does he desire to have the same form as the Lord, nor to live with Him side by side, nor to merge into His existence. Even if the Lord offers the pure devotee such rewards, he rejects them. The point is that a pure devotee is so much absorbed in the transcendental loving service of the Lord that he has no time to think of any benefit beyond his immediate engagement. Just as an ordinary materialistic businessman thinks of nothing else when he is absorbed in his business, a pure devotee, when engaged in the service of the Lord, does not think of anything beyond that engagement.
