Hanumān-mantra-kathana: Mantra-bheda, Nyāsa, Yantra, and Prayoga
अष्टच्छदेषु विलिखेत्प्रणवो वातुवात्विति । गोरोचनाकुंकुमेन लिखित्वा यंत्रमुत्तमम् ॥ १७४ ॥
aṣṭacchadeṣu vilikhetpraṇavo vātuvātviti | gorocanākuṃkumena likhitvā yaṃtramuttamam || 174 ||
Nas oito pétalas, inscreva-se a sílaba Oṁ juntamente com o mantra «vātu-vātu». Tendo sido escrito com gorocanā (pigmento amarelo) e açafrão, torna-se um yantra excelente.

It presents a precise method of yantra-lekhana where the Pranava (Oṁ) is placed on an eight-petalled design, indicating that ritual diagrams gain potency through correct mantra placement and sanctified materials.
By centering the yantra on Oṁ, the verse directs the practitioner toward reverent mantra-based worship; disciplined inscription and remembrance of sacred sound supports focused devotion and steadiness of mind.
It highlights applied ritual-technology—mantra-prayoga and yantra construction—showing procedural details (where to write the mantra and with which substances), a technical aspect aligned with Vedanga-style precision in practice.
