Summary of chapter 219 of the Agni Mahā Purana is as follows:

Agni discusses the recitation of Viṣṇu-Sahasranāma as composed within the Mahābhārata, taught by Bhīṣma to Yudhiṣṭhira. The chapter provides the proper pūrva-tantra and uttara-tantra for the recitation, including the dhyāna śloka and the phalasruti. Each of the thousand names is said to encapsulate one specific divine quality of Bhagavān. Agni declares that the daily recitation of the Sahasranāma yields the same merit as the gift of a thousand cows.
