11.36

又觀佛三昧經云。適施草坐地則大動。諸佛化作八萬佛樹師子之座。或有佛樹。高八千里四千里。或高百千由旬。一切佛樹具足八萬。大小不定。今釋迦樹最短。若干天衣。而布其上。

Also, the Guan Fo sanmei jing says: As soon as the grass seat was arranged, the earth shook greatly. The Buddhas transformed eighty thousand Buddha-trees with lion seats. Some Buddha-trees were eight thousand li or four thousand li tall; some were a hundred thousand yojanas tall. In all, the Buddha-trees numbered eighty thousand, of various sizes. Now Śākyamuni's tree was the shortest; various heavenly garments were spread upon it.
