肇論新疏 1.205

1.205

無滯而不通，故能混（融也）雜致（得也）淳；所遇而順適，故則觸物而一（中也）。躡前會歸中道也。

"Without obstruction and thus nothing not penetrated, one can blend (harmonise) the mixed to achieve (attain) the pure; wherever one encounters, one accords and is suited, hence contacting things, all is one (the middle)." This connects with what came before to return to the middle way.
