I am not used to the term Mayavada. I know Shankaracharya was an exponent of Advaita philosophy. It has nothing to do with Maya in the spiritual sense. Advaita philosophy is something that a jnani realizes at the end of his spiritual exercises. I would go with "kimfelix" and my understanding of the topic is similar. Only people with higher levels of understanding can go for Advaita philosophy. A layman should always begin his spiritual journey by bhakti yoga - Dualism. So it is pointless to discuss Advaita with a non initiated or a not so advanced in spiritual path.
