छन्दोऽनुष्टुप्सुराचार्यो देवता बीजमादिमम् । हृच्छक्तिर्दीर्घवह्नींदुयुगलेनांगकल्पना ॥ १२९ ॥
chando'nuṣṭupsurācāryo devatā bījamādimam | hṛcchaktirdīrghavahnīṃduyugalenāṃgakalpanā || 129 ||
Das Metrum ist Anuṣṭubh; die präsidierende Gottheit ist Surācārya, der göttliche Lehrer; und die ursprüngliche Samen-Silbe ist das bīja. Die hṛcchakti, die Herzensmacht, wird festgelegt, und die aṅga-nyāsa ist mit dem Silbenpaar „vahnī“ und „indu“ in langer (dīrgha) Form auszuführen.

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.
