The polemics among various philosophical schools is both unending and also a wonderful way for adherents to become clearer on their particular doctrine. Each school makes certain presuppositions upon which the school s philosophy is based. Advaita Vedanta philosophy is based upon its key concept of avidya/maya. Given its definition of avidya/maya everything else unfolds, consistently and coherently. Visistadvaita Vedanta, employing its key concepts of aprtak siddhi, challenges Advaita s doctrine. The same holds true for Dvaita Vedanta and its key concept of bheda.
