Among the niches in this altar frontal that contain images of the Buddha, the scene at the top right is from the Lotus Sutra, a fundemental Mahayana Buddhist text. When this doctorine was preached by Sakyamuni, the Buddha of the present era, to a great assembly of celestial and earthly beings, the relics of Prabhutaratna, the Buddha of the past, arose and Prabhutaratna materialized. The relief carving also includes an incense burner between two seated lions. The lion as a Buddhist guardian figure has been a common motif in Chinese art since the introduction of Buddhism in China.
