अथ यन्त्रान्तरं वक्ष्ये शुणु नारद सिद्धिदम् । अष्टारं विलिखेद्यन्त्रं श्लक्ष्णं कर्णिकया युतम् ॥ ९१ ॥
atha yantrāntaraṃ vakṣye śuṇu nārada siddhidam | aṣṭāraṃ vilikhedyantraṃ ślakṣṇaṃ karṇikayā yutam || 91 ||
ഇപ്പോൾ മറ്റൊരു യന്ത്രം ഞാൻ പറയുന്നു; കേൾക്കൂ, ഹേ നാരദ—ഇത് സിദ്ധിയിലേക്കുള്ള ഉപായമാണ്. എട്ട് അരകളുള്ള, മൃദുവായി നന്നായി തീർത്ത, കർണിക (മധ്യനാഭി)യോടുകൂടിയ യന്ത്രം വരയ്ക്കണം.

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.
