維摩義記 3.24

3.24

自下第二文殊具答。言「東方」者，辨其方所。言「度三十六恒河沙國」，彰其遠近。言「有世界名須彌相」，列其國名。佛號須彌，彰其佛稱。「身長八萬四千由旬」，明佛身相。「坐高八萬四千由旬嚴飾第一」，辨其坐相。言高八萬四千由旬，是其佛坐與佛等量，弟子之坐倍卑於此。出世善根之所出生，故嚴第一。

From here below, second, Mañjuśrī replies in full. The word "Eastern" specifies the directional location. Saying "passing thirty-six Ganges sands of lands" reveals the distance. Saying "there is a world named Sumeru Manifestation" lists the name of the land. The Buddha is named Sumeru, revealing the Buddha's appellation. "His body is eighty-four thousand yojanas tall" clarifies the appearance of the Buddha's body. "His seat is eighty-four thousand yojanas high, decorated and adorned foremost" explains the appearance of his seat. Saying that it is eighty-four thousand yojanas high means that the Buddha's seat is equal in measure to the Buddha; the disciples' seats are half as high as this. Being born of supramundane wholesome roots, its adornment is therefore foremost.
