Maya, (Sanskrit: ma: not, ya: this) in Hinduism, is many things. Maya is the illusion that the phenomenal world of separate objects and people is the only reality. For the mystics this manifestation is real, but it is a fleeting reality; it is a mistake, although a natural one, to believe that maya represents a fundamental reality. Each person, each physical object, from the perspective of eternity is like a brief, disturbed drop of water from an unbounded ocean. The goal of enlightenment is to understand this--more precisely, to experience this: to see intuitively that the distinction between me and the universe is a false dichotomy. The distinction between consciousness and physical matter, between mind and body, is the result of an unenlightened perspective.
Maya is also the name of an Asura, who was the father-in-law of the Lord of Lanka, Ravana and the father of Mandodari. He is the archnemesis of Vishwakarma, the celestial architect of the Gods. His knowledge and skills are compatible with Vishwakarma. When Lanka was destroyed by Hanuman, it was the King of Demons, Maya who had re-installed the beauty of that Island Kingdom.
