經。何以故　第二別釋也。文中有三。一明我空。二明法空。三明俱空。就我空中先徵後釋。此即初也。總問未來受持之人。何以獨成第一希有也。

Sūtra: Why is this? Second, this is the specific explanation.

Regarding the emptiness of self, there is first an interrogation and then an explanation. This is the first. It asks generally why the person who accepts and upholds it in the future alone accomplishes being the foremost rare one.
