Vivartavada states that although Brahman appears to undergo a transformation, in fact no real change takes place.
[3]The Brahma Sutras, the ancient Vedantins, most sub-schools of Vedānta,[3][web 2] as well as Samkhya argue for parinamavada.
[web 2] The "most visible advocates of Vivartavada," states Nicholson, are the Advaitins, the followers of Shankara.
"[web 2] Yet, scholars disagree on whether Adi Shankara and his Advaita system explain causality through parinamavada or through vivartavada.
[web 2][3][4] Scholars such as Hajime Nakamura and Paul Hacker state that Adi Shankara does not advocate Vivartavada and that his explanations are "remote from any connotation of illusion."
