大乘百法明門論疏 1.84

此即第二解別境五。言別境者，別緣諸境，名為別境。何者名別？且如其欲，希望前境名之為欲；不希望境即無有欲。希望之欲與不希望，二種有異，名之為別。乃至第五慧數，簡擇諸法名之為慧，不簡擇法不名為慧，簡擇之慧與不簡擇二種有異，名之為別。

This is the second [section], explaining the five viniyatas. As for 'viniyata' (specific object), they take specific objects as conditions, hence they are called viniyata. What is meant by 'specific'? For instance, regarding chanda, desiring an object before oneself is called chanda; if one does not desire the object, then there is no chanda. The chanda that desires and [the state of] not desiring—these two kinds are distinct, hence it is called 'specific'. And so on up to the fifth mental factor, prajñā: discriminating dharmas is called prajñā; not discriminating dharmas is not called prajñā. The prajñā that discriminates and [the state of] not discriminating—these two kinds are distinct, hence it is called 'specific'.
