अथ यन्त्रान्तरं वक्ष्ये शुणु नारद सिद्धिदम् । अष्टारं विलिखेद्यन्त्रं श्लक्ष्णं कर्णिकया युतम् ॥ ९१ ॥
atha yantrāntaraṃ vakṣye śuṇu nārada siddhidam | aṣṭāraṃ vilikhedyantraṃ ślakṣṇaṃ karṇikayā yutam || 91 ||
இப்போது இன்னொரு யந்திரத்தைச் சொல்கிறேன்; கேள், நாரதா—இது சித்தி பெறும் வழி. எட்டு ஆரங்களுடன், மென்மையாகச் சீராக, நடுக் கರ್ಣிகை (நாபி) உடைய யந்திரத்தை வரைய வேண்டும்.

It introduces a specific upāsanā-supporting yantra and states it as “siddhi-giving,” indicating that correct form (eight spokes and a central hub) is part of the discipline that supports focused attainment.
While the verse is technical, it supports devotional practice indirectly: a properly drawn yantra functions as a concentrative aid for mantra-japa and worship, helping the mind remain steady on the chosen deity or sacred intention.
It highlights ritual-technical procedure (prayoga)—the precise construction features of a yantra (aṣṭāra, ślakṣṇa, karṇikā)—a hallmark of applied Vedic sciences and temple/ritual praxis described in Book 1.3.
