Suta Goswami (narrating Shiva-puja procedures to the sages of Naimisharanya)
It prescribes ṣaḍaṅga-nyāsa—placing the mantra’s six limbs on their proper loci—so the worshipper’s body and speech become ritually aligned for Linga-pūjā, establishing protection (rakṣā) and fitness (adhikāra) for approaching Pati (Shiva).
By emphasizing nyāsa and mantric limbs, it presents Shiva as Pati who is accessed through śabda (mantra) and śakti (ritual potency): the bound pashu approaches liberation by sanctifying the embodied field where pasha operates, turning it into a vessel of Shiva’s presence.
Ṣaḍaṅga-nyāsa with protective and offering utterances (namaḥ, svāhā, vaṣaṭ, hūṃ, vauṣaṭ, phaṭ), a core preparatory practice in Shaiva pūjā that also functions yogically as mantra-śuddhi and rakṣā before deeper Pashupata-oriented worship.
