The Exposition of Nṛsiṁha Worship-Mantras, Nyāsa, Mudrās, Yantras, Kavaca, and Nṛsiṁha Gāyatrī
ह्रः हिरण्यगर्भरूप धारणान्ते च फट् ध्रुवः । ह्रौं अनौपम्यरूपधारिणास्त्रं ध्रुवस्ततः ॥ १९९ ॥
hraḥ hiraṇyagarbharūpa dhāraṇānte ca phaṭ dhruvaḥ | hrauṃ anaupamyarūpadhāriṇāstraṃ dhruvastataḥ || 199 ||
The syllable “hraḥ” is firmly fixed to be used at the end of the dhāraṇā for the form of Hiraṇyagarbha, together with the exclamation “phaṭ.” Then likewise, “hrauṁ” is fixed as the astra, the weapon-mantra that assumes the incomparable form.

It emphasizes disciplined mantra-application: specific bīja-syllables are “fixed” in precise positions (end of dhāraṇā, as astra), indicating that spiritual power is linked to correct form, placement, and intent in mantra-vidyā.
Though technical, it supports bhakti by prescribing focused dhāraṇā on a divine cosmic form (Hiraṇyagarbha) and protective sealing (phaṭ/astram), helping the practitioner maintain single-pointed remembrance and safeguarded worship.
It reflects mantra-prayoga discipline aligned with Vedāṅga concerns—especially śikṣā (correct syllabic utterance) and ritual precision—by specifying exact bīja forms and their prescribed placement (dhruva) within a mantra sequence.
