Procedure for Constructing the Fire-pit and Related Rites
तदर्धं दिशि संस्थाप्य भ्रामितं वर्तुलं भवेत् कुण्डार्धं कोणभागार्धं दिशिश्चोत्तरतो वहिः
tadardhaṃ diśi saṃsthāpya bhrāmitaṃ vartulaṃ bhavet kuṇḍārdhaṃ koṇabhāgārdhaṃ diśiścottarato vahiḥ
Letakkan separuh daripada ukuran itu pada arah yang ditetapkan dan putarkan; maka terhasil bentuk bulatan. Dengan demikian, separuh ukuran menentukan separuh kuṇḍa (lubang api), dan separuh bahagian sudut diletakkan pada arah—di bahagian luar—menghala ke utara.

Encyclopedic Reference: {"reference_type":"Procedure","entry_title":"Circular Kuṇḍa from Half-Measure (Directional Rotation)","lookup_keywords":["kuṇḍa-nirmāṇa","vṛttākāra","ardha-māna","diśā-nyāsa","uttara-bāhya"],"quick_summary":"Place the half-measure in the prescribed direction and rotate to generate a circle; use the half and corner-half portions to fix the kuṇḍa’s segment and its north-external directional offset."}
Concept: Ritual efficacy depends on correct measure (māna) and direction (diś).
Application: Use measured rotation and directional offsets to avoid doṣa (fault) in altar construction, ensuring homa is performed on a properly constituted field.

FAQs
It teaches a geometric procedure used in yajña-kuṇḍa layout: placing a half-measure in a specified direction and rotating it to generate a circular boundary, with additional placement rules for the corner-segment toward the northern exterior.
Beyond theology, it preserves applied ritual-engineering—directional planning and geometric construction for fire-altars—showing the text’s coverage of vastu/śulba-style practical knowledge alongside religious instruction.
Accurate kuṇḍa construction is treated as essential for a correctly performed yajña, supporting purity, proper offering-transmission to the deities, and the intended merit (puṇya) of the rite.
