首楞嚴義疏注經 4.169

4.169

虛空，藏性也。群相，七大也。真元無相，不守自性，隨緣現相，故云不拒發顯揮揚也。

Empty space is the nature of the [tathāgata]garbha. The manifold characteristics are the seven great elements. The real is originally without characteristics; not holding to its own nature, it manifests characteristics according to conditions. Therefore it says it does not refuse their manifestation and display.
