In plain words
Nimbārkācārya: exactly as in dualist worship, one must conceive of the relation between the jīvātma and Paramātma as the same as the relation between Puruṣa and Prakṛti, and worship accordingly — so says Vallabhācārya. In Śuddhādvaita worship, 'Kṛṣṇas tu bhagavān svayam' [Kṛṣṇa indeed is the Lord himself] — Lord Kṛṣṇa himself is, personally, Paramātma. Attaining that Ātma of all is precisely Śuddhādvaita's own liberation.
