ऊष्मान्त्यस्वरकिंजल्कं शेषार्णैः परिवेष्टितम् । कोणालंकृतभूतार्णभूगृहं यन्त्रमीशितुः ॥ २६ ॥
ūṣmāntyasvarakiṃjalkaṃ śeṣārṇaiḥ pariveṣṭitam | koṇālaṃkṛtabhūtārṇabhūgṛhaṃ yantramīśituḥ || 26 ||
Yantra Tuhan hendaklah mempunyai di pusatnya “debunga” yang terbentuk daripada vokal yang berakhir pada huruf ūṣman, dan dikelilingi oleh suku kata yang selebihnya. Sudut-sudutnya dihias dengan suku bhūta, dan ia ditempatkan dalam bhūgṛha, iaitu petak bumi berbentuk segi empat.

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.
