El metro es Anuṣṭubh; la deidad regente es Surācārya, el preceptor divino; y la sílaba-semilla primordial es el bīja. Se prescribe la hṛcchakti, el poder del corazón, y el aṅga-nyāsa debe realizarse con el par de sílabas «vahnī» e «indu» en su forma larga (dīrgha).

It formalizes a mantra’s ritual identity—metre (chandas), deity (devatā), seed (bīja), and inner potency (hṛcchakti)—so recitation aligns sound, meaning, and worship into an effective sādhana.
By prescribing devatā and bīja along with nyāsa, it shows that devotion is practiced through disciplined mantra-worship, where reverence is expressed via correct ritual placement and remembrance of the presiding deity.
Chandas (metre) is explicitly identified as Anuṣṭubh, and the verse also reflects applied ritual-phonetics/mantra-technology (nyāsa) through instructions about long vowels and coded syllable-pairs.
