2.254

弗沙菩薩曰。善不善為二。若不起善不善。入無相際而通達者。是為入不二法門　肇曰。弗沙星名也。什曰。生時所值因以為名。不善十惡也。善十善及涅槃也。

The Bodhisattva Puṣya said, "The wholesome and the unwholesome constitute duality. If one does not give rise to the wholesome or the unwholesome, enters the limit of the unconditioned (the absence of characteristics), and penetrates it thoroughly, this is entering the dharma gate of non-duality."
Sengzhao says, "Puṣya is the name of a star (constellation)." Kumārajīva says, "He was named after the constellation encountered at his birth. The unwholesome refers to the ten unvirtuous actions; the wholesome refers to the ten virtuous actions and nirvāṇa."
