Madhvaon Brahma Sūtra 3.3.59

• After the meditation for which an individual is eli- gible, the meditation with reference to particular objects of some one form of Brahman may be optionally made. This is said in the Brahma Tarka : “ For the sake of release the meditation to which one is fitted is indeed to be first practised, and then for the sake of getting rid of (the present) evils, etc., Nrisimha and other manifestations of Brahman are contemplated by the devotees according to their fitness ; others do not resort to this meditation at all as their purpose differs or as they have no such purpose, (i.e.i either because they have no evils to rid, or they think this may interfere with their chief meditation, or they may have everything accomplished by the chief meditation).
