A Ceremony of Revealing involves a target, willing or not, to be part of an Enactment that will reveal one or more aspects of an entity. These are not directed empowerments (ex: spells) that target an entity and use some form of divination to assess these things.
the ceremony assumes the target is part of the activity and has much less chance to resist (if not voluntary) and has less cost than far reaching divination rituals or spells. It has the equivalent effect of being able to assess anything that might be revealed by Aura Sight and more.
