“ ‘Pure devotees always reject the five kinds of liberation, which include living in the spiritual Vaikuṇṭha planets, possessing the same opulences as those possessed by the Supreme Lord, having the same bodily features as the Lord’s, associating with the Lord and merging into the body of the Lord. The pure devotees do not accept these benedictions without the service of the Lord.’
This is a verse from Śrīmad-Bhāgavatam (3.29.13).
