疏「今燈一喻雙喻緣了」下，第三結示喻旨兼指理源。「即涅槃二十六七」者，此是南經，北經即當二十八九。

From the Commentary's "Now the single metaphor of the lamp illustrates both the contributory and the revealing" downward: this is the third [section], concluding with an explanation of the import of the metaphor and additionally pointing to the source of the principle. "It is chapters twenty-six and twenty-seven of the Nirvāṇa [Sūtra]": this refers to the Southern edition; in the Northern edition it corresponds to chapters twenty-eight and twenty-nine.
