Garuḍa’s Assault on the Devas and the Fire-Barrier (अमृत-रक्षा-युद्धम्)
इति श्रीमहाभारते आदिपर्वणि आस्तीकपर्वणि सौपर्णे अष्टाविंशो5ध्याय:
iti śrīmahābhārate ādiparvaṇi āstīkaparvaṇi sauparṇe aṣṭāviṁśo 'dhyāyaḥ
Thus ends the twenty-eighth chapter of the Sauparṇa section within the Āstīka sub-parvan of the Ādi Parvan of the revered Mahābhārata.
गरुड उवाच
This line is a colophon marking the end of a chapter and locating it within the Mahābhārata’s internal structure; its purpose is organizational rather than doctrinal.
No narrative action occurs here; it simply announces the completion of the 28th chapter of the Sauparṇa portion within the Āstīka sub-parvan of the Ādi Parvan.
