Philosophically, the Smarta tradition emphasizes that all idols (murti) are icons of "saguna" Brahman, a means to realizing the abstract Ultimate Reality called nirguna Brahman. The five or six icons are seen by Smartas as multiple representations of the one Saguna Brahman (i.e., a personal God with form), rather than as distinct beings. The ultimate goal in this practice is to transition past the use of icons, then follow a philosophical and meditative path to understanding the oneness of Atman (soul, self) and Brahman (metaphysical reality) – as "That art Thou".
