維摩經略疏 2.104

2.104

若約觀心者，因緣所生即有為之類，從假入空破有為集成無為之類也。若入假名中道，破無為未盡，皆名無為之類。

If considered in terms of contemplation of mind: that which is born of causes and conditions belongs to the category of the conditioned; entering emptiness from the provisional breaks the accumulation of the conditioned and constitutes the category of the unconditioned. If one enters the Middle Way of provisional names and has not completely broken the unconditioned, these are all termed the category of the unconditioned.
