भीष्म उवाच
This line is a colophon marking the close of a chapter; it signals that the chapter’s subject was the exposition of yogic disciplines (yogācāra) within the Mokṣa-dharma portion of the Śānti Parva.
The text is concluding a discourse attributed to Bhīṣma’s instruction in the Śānti Parva; the verse functions as an editorial/structural closure identifying the work (Mahābhārata), the parva (Śānti), the section (Mokṣa-dharma), the chapter title, and the chapter number.
