6.427

第二辨相中解乞食文有二：初開為二；次別解二；後辨開合意。隨得乞食者，泰法師云：隨舊門從往還家。

Under the second, distinguishing characteristics, the text explaining begging alms has two parts: first, dividing into two; next, explaining the two separately; finally, explaining the intention behind opening and combining. As for 'begging alms as they are obtained', Master Tai says: following one's customary route, going back and forth to families.
