Are Cognitive States Self-Revealing?

According to the Nyaya school of Hindu philosophy, a cognitive state reveals its object but not itself and is revealed by another cognitive state.  Other Hindu philosophers of the Advaita Vedanta philosophical school and Prabhakara (8^th century), however, hold that a cognitive state reveals both its object and itself.  I shall discuss the nature of consciousness and self-consciousness and reconstruct how the Nyaya can respond to the formidable arguments offered by the Advaita and Prabhakara.
