Vidya Category: {"primary_vidya":"Shilpa","secondary_vidya":"Vastu","practical_application":"Provides modeling instructions for forehead–nose–face–neck transitions and a proportional reduction rule (one-fifth relative to arm measure) for a corresponding ‘arm-less’/reduced component in the canon.","sutra_style":true}
Encyclopedic Reference: {"reference_type":"Procedure","entry_title":"Modeling Forehead–Nose–Face–Neck and One-fifth Reduction from Arm Measure","lookup_keywords":["lalāṭa-nāsikā","vaktra-grīvā","vivartayet","pañcamāṃśa","bhuja-māna"],"quick_summary":"Instructs shaping of key head/neck contours and applies a one-fifth subtraction from the arm measure to derive a reduced corresponding dimension per the proportional canon."}
Concept: Canonical form emerges from both geometry (fractions) and plastic modeling (vivartana)
Application: When transferring measures across limbs/features, apply stated fractional reductions to maintain visual coherence; model transitions smoothly to avoid harsh breaks in mukha–grīvā.

Sandhi Resolution Notes: lalāṭanāsikāvaktragrīvāyāñca → lalāṭa-nāsikā-vaktra-grīvāyām + ca; bhujācca → bhujāt + ca. The middle portion of the provided Devanagari/IAST contains critical apparatus/variant readings (takapāṭhaḥ... cihnitapustakapāṭhaḥ...) and is excluded from pada analysis as non-verse commentary.

FAQs
It gives shilpa/vaastu technical guidance on iconometric proportioning—how to contour key facial/neck features and how to reduce a dimension by one-fifth using the arm as a standard unit.
Beyond theology, the Agni Purana preserves applied sciences like Shilpa- and Vastu-shastra, including practical proportional rules used by sculptors and temple-artisans for making images.
Correct proportions are treated as dhārmic accuracy in image-making; following the canon supports proper consecration and worship, aligning the crafted form with scriptural standards and thus with religious merit.
