It links inner yogic synthesis (ātma-catuṣka-yoga) with a specific sacred syllable (“arka”) and prescribes nyāsa—ritual placement on key bodily centers—so the practitioner internalizes mantra-power rather than keeping it merely verbal.
While technical, the nyāsa instruction functions as embodied devotion: the mantra is installed on the body’s sacred points, turning the devotee’s own form into a support for steady remembrance and worship.
It highlights applied mantra-science: forming a specific akṣara through “yoga” (combination) and using a ritual procedure (nyāsa) that belongs to the technical discipline of mantra-prayoga found in Vedanga-oriented sections.
