成唯識論演祕 7.94

7.94

釋曰：定境能令善品相續，名為實義。或簡遍計所執之境，名之為實。量云：定所現境虛非實有；依清緣現；猶如水月。「又如變化，依此變化說名變化。雖無有實，而能化者無有顛倒，於所化事勤作功用。菩薩亦爾，雖無遍計所執有情，於依他起諸有情類，由哀愍故，而往彼彼諸所生處攝受自體。」

The explanation says: The objective realm of meditative concentration can cause the continuity of wholesome dharmas, hence it is called 'real referent'. Alternatively, it is called 'real' to exclude the imagined realm. The formal proof is formulated: The realm manifested by meditative concentration is empty and not truly existent; because it manifests dependent on clear conditions; just like the moon in the water. [The sūtra says:] 'Furthermore, it is like an apparition: spoken of as an apparition dependent on this apparition. Although it is without reality, the magician is without distortion and diligently applies effort toward the conjured entity. Bodhisattvas are also like this: although there are no imagined sentient beings, out of compassion toward sentient beings that are dependently originated, they proceed to those various places of birth and take on a self-existence.'
