The Exposition of the Table of Contents (Anukramaṇī) of the Agni Purāṇa

此处阐明宇宙毁灭(pralaya,劫坏)的诸相,解析具身众生(身躯之构成),叙述诸地狱,并宣说至上的瑜伽教法。
Suta (Anukramanika-style chapter summary narration, recounting the Purana’s contents)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhayanaka
This verse functions as a table-of-contents marker: it signals that the text teaches impermanence through pralaya, ethical causality through naraka descriptions, self-inquiry through analysis of embodiment, and liberation-oriented discipline through Yoga.
Indirectly: by emphasizing pralaya and naraka it urges detachment and righteous living, and by placing “supreme Yoga teaching” as the culmination it frames spiritual practice as the means to transcend fear and bondage—often aligned in the Narada Purana with devotion to Vishnu as the liberating orientation.
No specific Vedanga (like Vyakarana, Jyotisha, or Kalpa) is named in this verse; it is a thematic summary pointing instead to doctrinal sections on cosmology (pralaya), ethics (naraka), anthropology (sharira), and soteriology (yoga).
