法華義疏 9.203

9.203

淨土佛妙尚是應而非真，則顯釋迦穢身彌是迹而非本，所以俱集淨土分身之佛有其深旨也。

Even the wondrousness of the Buddhas of the pure lands is still a response and not the real; this reveals that Śākyamuni's defiled body is all the more a trace and not the fundamental. Therefore, gathering the emanated Buddhas of the pure lands together has a profound meaning.
