法華論疏 1.102

1.102

一上支下支門者，謂總相、別相也。總相在前為上支，別相在後為下支也。欲辨總別二義枝條不同，故稱為支也。攝取事門者，以十三句攝取菩薩要功德事，故云攝取事門。

"The approach of higher and lower branches" refers to the general characteristic and the particular characteristics. The general characteristic is in front and is the higher branch; the particular characteristics are behind and are the lower branches. Wishing to distinguish that the two meanings—general and particular—differ like branches, they are called "branches." "The approach of gathering affairs": because the thirteen phrases gather the essential affairs of virtue of the bodhisattvas, it is called the approach of gathering affairs.
