1.53

其名曰等觀菩薩　此下四列名。叡曰。此諸菩薩或以功行為名。亦有因相得稱非唯一途。亦如今人字耳。宜為可望文。消息無定義也。什曰。等觀四等觀眾生也。

"Their names were: Equal Contemplation Bodhisattva (Samadarśin)" From here down is the fourth [section], listing their names. Sengrui says: "These various bodhisattvas were named either after their meritorious practices, or obtained their appellations due to physical marks; it was not by one single way, just as people today have courtesy names. One should look at the text to appreciate the sense; there is no fixed definition." Kumārajīva says: "'Equal contemplation' means observing sentient beings with the four immeasurables."
