The liberations are sārṣṭi [achieving opulences equal to those of the Lord], sārūpya [having a form the same as the Lord’s], sāmīpya [living as a personal associate of the Lord] and sālokya [living on a Vaikuṇṭha planet]. Devotees never accept sāyujya, however, since that is oneness with Brahman.
Those engaged in devotional service according to the ritualistic principles mentioned in the scriptures attain these different kinds of liberation. But although such devotees can attain sārṣṭi, sārūpya, sāmīpya and sālokya, they are not concerned with these liberations, for such devotees are satisfied only in rendering transcendental loving service to the Lord. The fifth kind of liberation, sāyujya, is never accepted even by devotees who perform only ritualistic worship. To attain sāyujya, or merging into the Brahman effulgence of the Supreme Personality of Godhead, is the aspiration of the impersonalists. A devotee never cares for sāyujya liberation.
