Here dwell the Earth Protectors and Rigdens, who rule over all Shambhala and radiate the heart of all true human law. Kalapa is a vast square with high bright ruby walls, surmounted by golden balustrades. Its four gates are made from sapphire, yellow diamond, ruby and emerald. Within the walls are the inner gates and courtyards paved with white opal. In the center, on a platform of pearl, is a great palace, the Kalapa Court.
