Mayavada (Sanskrit maya, illusion, and vada, doctrine) is a term used to pejoratively refer to the Advaita philosophy of Adi Shankara. It is not used by the followers of the Advaita philosophy to refer to themselves. It is generally used as a derogatory term, by some Dvaita schools. Mayavada pertains to a doctrine where the personal forms of God are considered to be influenced by Maya (illusion) and only the one-ness of the Impersonal Brahman is considered to be the Absolute Truth.
According to Dvaita philosophy, Mayavada is an incorrect understanding of the nature of Supreme and it is strongly refuted by saints like Madhavacarya, Lord Chaitanya Mahaprabhu, Baladeva Vidyabhusana, Bhaktisiddhanta Saraswati Thakur and most recently by Bhaktivedanta Swami .
Dr. S. Radhakrishnan, mentions in his Indian Philosophy vol.2 that Nyayakosa includes Samkhya and Advaita Vedanta under naistika, i.e. unorthodox systems, or in other words that mayavadi is an atheist.[1]
The prominent debate on relevance of Mayavada come from International Society for Krishna Consciousness from the purports in the Bhagavad-Gītā As It Is
