The Description of the Sarvatobhadra Maṇḍala (सर्वतोभद्रमण्डलकथनम्)
कोष्ठकानां भद्रकञ्च मध्ये षोडशकोष्ठकैः पार्श्वे वीथीं ततश्चाष्टभद्राण्यथ च वीथिका
koṣṭhakānāṃ bhadrakañca madhye ṣoḍaśakoṣṭhakaiḥ pārśve vīthīṃ tataścāṣṭabhadrāṇyatha ca vīthikā
Entre los compartimentos (koṣṭhakas), colóquese en el centro un bhadraka auspicioso; a los lados dispónganse dieciséis compartimentos; luego establézcase una vīthī (pasaje/avenida) y, después, ocho bhadrakas, así como una vīthikā (pasaje menor).

Sandhi Resolution Notes: भद्रकञ्च = भद्रकम् + च. ततश्चाष्टभद्राणि = ततः + च + अष्टभद्राणि.
It teaches a Vastu-shastra layout rule: how to arrange compartments (koṣṭhakas) with a central bhadraka, side units counted as sixteen, and the placement of passages (vīthī/vīthikā) plus eight additional bhadrakas—i.e., a counted, modular plan for a structure or mandala.
Beyond myth and devotion, the Agni Purana preserves applied technical sciences; here it encodes architectural planning terminology (koṣṭhaka, bhadraka, vīthī) and numerical design constraints typical of classical Indian Vastu treatises.
In Vastu thought, correct proportioning and auspicious placement (bhadraka, ordered passages) harmonize the built space with dharma and cosmic order, supporting purity, stability, and beneficial results for the occupants and ritual activity performed there.
