It teaches a Śaiva nyāsa/vinyāsa mapping: the “second” mantra/form (Sadyodeva/Sadyōjāta) is placed in the heart with aṅga-associations, and the “fourth” corresponds to the head, following Īśvara’s designated naming scheme.
Beyond mythic narration, it preserves precise, practice-oriented ritual technology—mantra classification, body-locus assignments (heart/head), and aṅga-nyāsa conventions—showing the Agni Purāṇa’s coverage of Tantric-ritual procedure alongside other sciences.
Correct nyāsa is held to purify the practitioner’s body as a ritual seat of the deity, stabilizing concentration and sanctifying worship so the mantra is “installed” properly, supporting merit (puṇya) and effective devotion.
