In Freemasonry, the chamber of reflection (also called, the room of reflection, reflection cabinet or meditation cabinet) is the place where part of the initiation process takes place. It is used as a test of isolation during which the recipient is invited to perform some introspection. This is facilitated by the presence of symbolic objects and evocative sentences which may differ slightly depending on the rites. This phase of isolation generally begins the initiation ritual that a layman experiences when he enters a Masonic course.
