When a form of Kṛṣṇa is nondifferent from the original form but is less important and exhibits less potency, it is called  svāṁśa . Examples of the  svāṁśa  expansion can be found in the quadruple forms of the Lord residing in their respective places, beginning with Saṅkarṣaṇa, Pradyumna and Aniruddha and including the  puruṣa-avatāras ,  līlā-avatāras ,  manvantara-avatāras  and  yuga-avatāras .
