釋摩訶衍論 3.19

3.19

論曰：性虛空理有十種義。云何為十？一者無障礙義，諸色法中無障礙故；二者周遍義，無所不至故；三者平等義，無簡擇故；四者廣大義，無分際故；五者無相義，絕色相故；六者清淨義，無塵累故；七者不動義，無成壞故；八者有空義，滅有量故；九者空空義，離空著故；十者無得義，不能執故。是名為十。如是十事，義用差別，若據其體無別而已。此虛空理，二種淨智親所內證，相應俱有不相捨離。二虛空中當何虛空？謂清淨虛空，非染淨虛空。染淨虛空字事差別其相云何？頌曰：

Fourth is the meaning of vastness, because it is without boundary. Fifth is the meaning of signlessness, because it is devoid of material signs. Sixth is the meaning of purity, because it is free from the defilements of dust. Seventh is the meaning of immobility, because it is without formation or disintegration. Eighth is the meaning of having emptiness, because it destroys the measurement of existence. Ninth is the meaning of the emptiness of emptiness, because it departs from attachment to emptiness. Tenth is the meaning of unattainability, because it cannot be grasped. These are called the ten. Such ten matters are distinguished by their meaning and function; with regard to their essence, there is simply no distinction. This principle of space is directly and internally realized by the two kinds of pure wisdom, being associated and coexisting without abandoning one another. Between the two kinds of space, which space is this? It refers to pure space, not defiled-and-pure space. What is the character of the distinction in literal meaning of defiled-and-pure space? The verse says:
