Great Treasure Chamber [大宝坊] ( Daihō-bō): The vast court where the Great Collection Sutra was preached. According to this sutra, when Shakyamuni was on Eagle Peak in Magadha, India, using his powers of meditation, he made a great court adorned with precious treasures appear between the world of desire and the world of form. He ascended to that court, the Great Treasure Chamber, and expounded his teachings there.
