Fu Andun 福安敦 and Gu Zhengmei 古正美 have estimated that this sūtra was composed under the Sui. The text was among the sources of the commentary on the Mahāmegha-sutra associated with the reign of Wu Zetian.

Strickmann claims that the Puxian pusa shuo zhengming jing 普賢菩薩說證明經 T2879 is a Chinese apocalyptic composition which dates from the late sixth century. The sūtra refers to the “white-robed religious and laymen” which relates to the whitening of religious robes characteristic of later Maitreyan movements. For more on this text, Strickmann refers to Forte, Political Propaganda, pp. 271-280.
