It links mantra-structure (twelve- and eight-syllabled forms) with cosmic principles—Ādityas and the eightfold Prakṛti—teaching that mantra is not mere sound but a mapped spiritual technology aligning the practitioner with universal forces.
By presenting mantras as deity-connected (Āditya-linked) and principle-embodying (Prakṛti-linked), it implies that devotional japa becomes effective when the devotee contemplates both the devatā and the tattva embodied by the mantra.
It highlights Chandas/phonetics-based mantra classification (by syllable-count) and a Jyotiṣa-style deity mapping (Ādityas), showing how technical mantra metrics and cosmological correspondences are used in ritual and recitation.
