Mantra-Māhātmya and Sādhana of Kārtavīryārjuna
Nyāsa, Yantra, Homa, and Dīpa-Vrata
ऊष्मान्त्यस्वरकिंजल्कं शेषार्णैः परिवेष्टितम् । कोणालंकृतभूतार्णभूगृहं यन्त्रमीशितुः ॥ २६ ॥
ūṣmāntyasvarakiṃjalkaṃ śeṣārṇaiḥ pariveṣṭitam | koṇālaṃkṛtabhūtārṇabhūgṛhaṃ yantramīśituḥ || 26 ||
Le yantra du Seigneur doit avoir en son centre le « pollen » formé des voyelles se terminant par les lettres ūṣman, et être entouré des syllabes restantes. Ses angles sont ornés des syllabes bhūta, et l’ensemble est placé dans un bhūgṛha, l’enclos carré de terre.

It teaches that a deity’s yantra is not decorative art but a disciplined placement of sacred sounds (varṇas), where the center, enclosure, and corners encode spiritual order—making the diagram a support for focused worship and mantra-sādhana.
Bhakti here is expressed through precise upāsanā: the devotee honors the Lord by constructing the yantra according to revealed sound-structure, treating mantra and form as a unified aid to remembrance and worship.
It highlights śikṣā/varṇa-vinyāsa (phonetic-letter arrangement) applied to ritual technology—how specific classes of letters (vowels, ūṣman-ending groups, and other arṇas) are placed in the yantra’s center, perimeter, and corners.
