注維摩詰經 8.34

8.34

什曰：二十八宿中鬼星名也。生時所值宿，因以為名也。肇曰：弗沙，星名也。菩薩因以為字焉。

[Kumāra]jīva says: This is the name of the Ghost constellation [Puṣya] among the twenty-eight constellations. Being born under this constellation, he was named after it. [Seng]zhao says: Puṣya is the name of a star; the bodhisattva took his name from it.
