शब्दब्रह्मतनुवर्णनम् — Description of the Form of Śabda-Brahman
आभिचारिकमत्यर्थं प्रायस्त्रिंशच्छुभाक्षरम् । यजुर्वेदसमायुक्तं पञ्चविंशच्छुभाक्षरम्
ābhicārikamatyarthaṃ prāyastriṃśacchubhākṣaram | yajurvedasamāyuktaṃ pañcaviṃśacchubhākṣaram
For ābhicārika rites—meant for forceful pacification or for countering hostile influences—the mantra is generally of thirty auspicious syllables. When conjoined with Yajurvedic formulae, it is of twenty-five auspicious syllables.

It highlights mantra-niyama (discipline): Shiva’s worship is not random but aligned with measured, auspicious sound (akṣara), so the practitioner’s intention is supported by a precise, sattvic mantra structure.
In Saguna Shiva worship—often centered on the Linga—mantra is the primary link between devotee and Lord; this verse explains that particular ritual aims (like śānti/protection) traditionally employ specific syllable-measures, sometimes combined with Yajurvedic recitations.
It suggests using properly measured Shiva-mantras for protective/śānti purposes, and where prescribed, pairing them with Yajurvedic formulas—performed as japa or homa under scriptural guidance rather than improvisation.
