4.227

論「且應辨得」者，辨差別中，先明得、後明非得，故言「且」也。自此已下有兩頌半明得差別。此一頌半，五門分別。

Regarding "One should first explain possession": within the explanation of distinctions, possession is explained first and non-possession is explained later; hence it says "first". From this point onward there are two and a half stanzas explaining the distinctions of possession. These one and a half stanzas are analyzed across five headings.
