In Hindu philosophy, ignorance of the True Self causes ego and the perceived distinction between consciousness and physical matter, between mind and body. This ignorance is the cause of karma debt and reincarnation. The state of illusion, or Maya, gives rise to egoism and desire.
In Indian religions, Maya (Sanskrit: माया māyā) is personified as a deity centered around the illusion of the duality or polarity of the Universe. For a person seeking enlightenment, the main goal is to bridge this polarity, and see that the Self and the Universe are one.
