二、明通別者，還束前三以為通別。如是六義即是通序，現瑞序述合為別序。諸經通以六義為首，故名通序。眾經之初現瑞不同序述各異，有所表發故云別序。今因別名，則有別序、有別言教，若因通名則有通序，行理通別因此而有兩序。

Second, clarifying the common and specific: This gathers the preceding three to form the common and specific. The six conditions such as 'thus' are the common preface; manifesting auspicious signs and the prefatory narration combine to form the specific preface. Sūtras commonly take the six conditions as their head, hence it is called the common preface. At the beginning of the various sūtras, the manifestations of auspicious signs differ and the prefatory narrations are distinct, each indicating and initiating something, hence called the specific preface. Now, because of the specific name, there is a specific preface and a specific verbal teaching; if because of the common name, there is a common preface. The commonality and specificity of practice and principle give rise to these two prefaces on this basis.
