सूर्पभक्तैः शिलायां तु भागं स्वाङ्गुलमुच्यते द्व्यङ्गुलं गोलकं नाम्ना कालनेत्रं तदुच्यते
sūrpabhaktaiḥ śilāyāṃ tu bhāgaṃ svāṅgulamucyate dvyaṅgulaṃ golakaṃ nāmnā kālanetraṃ taducyate
บนศิลาวัด ขีดแบ่งที่ทำด้วยรอยของสุรปะ (กระด้งฝัด) เรียกว่า ‘สวางคุละ’ คือความกว้างนิ้วของตนเอง ส่วนขนาดสองอังคุละเรียกว่า ‘โกลกะ’; และสิ่งเดียวกันนี้เรียกอีกชื่อว่า ‘กาลเนตร’

Encyclopedic Reference: {"reference_type":"Definition","entry_title":"Svāṅgula, Golaka (Kālanetra): aṅgula-based measures on measuring stone","lookup_keywords":["svāṅgula","aṅgula","golaka","kālanetra","māna-śilā"],"quick_summary":"Defines practical workshop units: a single aṅgula mark on the measuring stone is ‘svāṅgula’; two aṅgulas form ‘golaka’, also termed ‘kālanetra’, enabling repeatable proportional work."}
Concept: Measure (māna) is the bridge between idea and form; naming units stabilizes transmission of craft knowledge.
Application: When training artisans or documenting designs, define and calibrate units (aṅgula multiples) on a standard reference slab to avoid drift across hands and generations.

FAQs
It defines precise traditional units of length used in Vāstu/Śilpa work—identifying ‘svāṅgula’ (a finger-breadth) and naming the two-aṅgula measure as ‘golaka’, also known as ‘kālanetra’—for standardized marking on a measuring slab.
Beyond theology, the Agni Purāṇa preserves practical technical vocabulary for architecture and craft—codifying measurement units and their synonyms—showing its role as a compendium that includes design science (Vāstu/Śilpa) alongside ritual and doctrine.
Accurate measurement is treated as a dharmic requirement in sacred building and iconography: correct proportions prevent defects (doṣa) and support auspiciousness, ensuring that construction aligns with prescribed order (niyama) and yields meritorious outcomes.
