From the Introduction: The parts of this temple which are accessible by the public, consist only of this one grand hall. It can be segmented into the nave and a transept. The area where they meet is called the crossing. The crossing and the transept are the parts holding the lay worshipers during the mess while the raised choir holds the altar and seats for the clergy. These are the only seats available in the temple. Lay worshipers are expected to stand or kneel on the tiled stone floor. A prominent feature of the nave is a large pool just past the entrance, which is usually used for ritual washings. Two stairs lead down to doors leading to the crypt, which are usually locked.
