The whole east slope is devoted to the illustration of the Universal Gate of Avalokitesvara in the Lotus sutra, some scenes of which extend to the north slope. The scenes can be divided into two parts: Avalokitesvara rescuing people from trouble and the thirty-three manifestation of Avalokitesvara. The former refers to the records that Avalokitesvara can help people out of eight kinds of disasters, free people from the three evil things: lust,anger, and imbecility, satisfy people\'s desire for obtaining a daughter or a son; and the latter refers to that Avalokitesvara can manifest as the Buddha,Pratyekabuddha,Shravaka, Brahma, Indra and etcs. In composition, the paintings of Pratyekabuddha consists of three levels, one above another, and the episodes also develop from right towards left in horizontal bands.However, the exact depiction of these scenes has broken the limits of the space and time, and then it can be divided into three parts: the upper band is devoted to one of the eight salvations, namely saving people from being robbed.The middle band and the right half of the lower band are covered with dense scenes of the other seven salvation. The left part of the lower band is used for the thirty-three manifestations, which are not completely rendered. Due to the changes of colors, many scenes have become obscured and the characters and costume styles are hard to identify. The scenes of this part also extend to the neighboring east side of the north slope.
