This rectangular niche, also known as Avalokitesvara Hall, measures 3.8 m wide, 6.4 m high, and 3.3 m deep. On the back wall are Avalokitesvara Bodhisattva on the left and Mahasthamaprapta Bodhisattva on the right.
Avalokitesvara is depicted with smooth, fine features, slightly closed eyes, and a tall headdress. The headdress is adorned with a small seated Buddha image. The right hand is raised to the shoulder, while the left holds a porcelain bowl to the chest. The Bodhisattva wears chest ornaments and a loose robe over a densely draped lower garment. The folds in the cloth are carved in such a way as to give it a thick, heavy appearance, and it is decorated with colorful patterns.
Mahasthamaprapta Bodhisattva wears clothing similar to that of Avalokitesvara; however, the headdress is slightly different, with a ribbon hanging from it on either side, and the chest ornaments take a different shape. Mahasthamaprapta stands with one hand hanging naturally; the other has been damaged. Both figures exude a sense of calm, solemn dignity.
