iti śrīmahābhārate śāntiparvaṇi mokṣadharmaparvaṇi nārāyaṇīye ekonacatvāriṃśad-adhika-triśatatamo 'dhyāyaḥ
Thus, in the Śrī Mahābhārata, within the Śānti Parva—specifically the Mokṣa-dharma section, in the Nārāyaṇīya—ends the three-hundred-and-fortieth chapter (i.e., the 340th).
भीष्म उवाच
This line is a colophon marking the end of a chapter; it does not add new doctrine, but situates the teaching within the Mokṣa-dharma and Nārāyaṇīya framework—i.e., liberation-oriented dharma and devotion/philosophy centered on Nārāyaṇa.
The text is concluding a chapter in the Śānti Parva. It functions as an editorial/structural closure, identifying the parva, sub-parva, section, and the chapter number.
