तदर्धं दिशि संस्थाप्य भ्रामितं वर्तुलं भवेत् कुण्डार्धं कोणभागार्धं दिशिश्चोत्तरतो वहिः
tadardhaṃ diśi saṃsthāpya bhrāmitaṃ vartulaṃ bhavet kuṇḍārdhaṃ koṇabhāgārdhaṃ diśiścottarato vahiḥ
ఆ ప్రమాణంలోని అర్ధభాగాన్ని నిర్దిష్ట దిశలో స్థాపించి తిప్పితే వృత్తాకారం ఏర్పడుతుంది. ఆ అర్ధప్రమాణమే కుండం యొక్క అర్ధాన్ని నిర్ధారిస్తుంది; అలాగే కోణభాగంలోని అర్ధాన్ని కూడా దిశలో—బాహ్యంగా—ఉత్తర వైపున ఉంచాలి.

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.
