This illustration was originally situated on the outer wall of the north corridor. It illustrates a story from the Abhiniskramana Sutra in which Sakyamuni Buddha, in a previous life, made offerings to various Buddhas, which helped him to attain Buddhahood. This is one of the more common themes from the Uighur (mid-9th century–1209) ruling over Gaochang period.
The standing Buddha in the center of the image forms the vitarka (teaching) mudra with a raised hand. The figure is surrounded by a triple-layered nimbus and aureole, with jewels and flames decorating the outer layers. The Buddha wears a densely draped monastic robe, an ornament extending to the knees, and sandals. He is depicted standing with each foot on a lotus pedestal, supported by a wooden platform on a pond. From top to bottom, a Bodhisattva, a monk, and three figures kneeling to make offerings can be seen on the left. On the right, from top to bottom, there is a monk, a Bodhisattva, a figure making offerings, and a figure with joined palms. A donkey and camel carrying materials are shown below.
