Encyclopedic Reference: {"reference_type":"Definition","entry_title":"Prasada breadth types (uttama, madhyama, kanishtha) by pada proportion","lookup_keywords":["pitha-ucchraya","uttamanca","prasada-ardha-vistara","pada","madhyama-kanishtha"],"quick_summary":"The standard breadth is set as half by the pitha/upper-course measure; reducing by one pada yields the medium type, while the small type is reckoned as half of the best standard."}
Concept: Saṃkhyā/pramāṇa: sacred architecture as applied mathematics with named typologies.
Application: When designing, fix a standard breadth, then derive variants by modular subtraction (pada) to maintain harmony.

It defines a Vastu-shastra sizing rule for a prāsāda: the standard breadth is set at half-measure, with ‘medium’ obtained by reducing one pada (module), and ‘small’ derived as half of the ‘best’ standard.
Beyond mythology, the Agni Purana preserves applied technical knowledge—here, architectural metrology and typology (uttama–madhyama–kaniṣṭha) used by temple builders and planners.
In Purāṇic Vastu, correct proportioning of a shrine is treated as dharmic alignment—supporting a stable, auspicious abode for worship, which is believed to enhance the merit and efficacy of ritual practice performed there.
