佛說觀普賢菩薩行法經 1.16

1.16

「爾時，十方面一一方有一菩薩乘六牙白象王，亦如普賢等無有異，如是十方無量無邊滿中化象。普賢菩薩神通力故，令持經者皆悉得見。

"At that time, in each of the ten directions, there is a bodhisattva riding a six-tusked white elephant king, equal to and no different from Samantabhadra; thus the ten directions are filled with immeasurable, boundless manifested elephants. By the supernatural power of Samantabhadra Bodhisattva, the upholders of the sūtra are all enabled to see them.
