Helārāja interprets the fivefold division as including karmapravacanīyas.[17] But the fourfold division, mentioned by the great commentator, is proper, since karmapravacanīyas distinguish a connection produced by a particular kind of verb, and thus, as marking out a particular kind of connection and so marking out a particular kind of verb, they are really included in compounded prepositions (upasargas).[18]
