Śānti Parva, Adhyāya 52 — Bhīṣma’s Humility Before Kṛṣṇa and the Granting of Boons
इस प्रकार श्रीमह्याभारत शान्तिपर्वके अन्तर्गत राजध्मानुशासनपर्वमें श्रीकृष्णवाक्यविषयक इकक््यावनवाँ अध्याय पूरा हुआ
iti prakāraṃ śrīmahābhārate śāntiparvake antargata rājadharmānuśāsanaparvaṇi śrīkṛṣṇavākyaviṣayaka ekapañcāśattamo 'dhyāyaḥ samāptaḥ
Thus, in the Śrī Mahābhārata, within the Śānti Parva—specifically in the section on the instruction concerning the duties of kings—ends the fifty-first chapter, whose subject is the discourse of Śrī Kṛṣṇa.
वायुदेव उवाच
This line is a colophon rather than a doctrinal verse: it signals the completion of a chapter in the Rājadharma (royal duty) instruction section, framing Śrī Kṛṣṇa’s speech as authoritative ethical counsel on righteous governance.
The text is closing the chapter: it formally states that the fifty-first chapter—centered on Śrī Kṛṣṇa’s words—has ended within the Śānti Parva’s Rājadharmānuśāsana section.
