उमामहेश्वरव्रतं—पञ्चाक्षरमन्त्रस्य माहात्म्यं, न्यासः, जपविधिः, सदाचारः, विनियोगः
बीजं शक्तिं स्वरं वर्णं स्थानं चैवाक्षरं प्रति वामदेवो नाम ऋषिः पङ्क्तिश्छन्द उदाहृतः
bījaṃ śaktiṃ svaraṃ varṇaṃ sthānaṃ caivākṣaraṃ prati vāmadevo nāma ṛṣiḥ paṅktiśchanda udāhṛtaḥ
For each syllable—its bīja (seed), śakti (power), svara (intonation), varṇa (phoneme-class), and sthāna (place of articulation)—the ṛṣi is declared to be Vāmadeva, and the meter is taught as Paṅkti.
Suta Goswami (narrating mantra-lakṣaṇa details to the sages of Naimisharanya)
It establishes the mantra-technical framework used in Linga-pūjā—defining bīja, śakti, svara, varṇa, and sthāna—so the practitioner applies correct recitation and nyāsa, aligning Pashu (the soul) toward Pati (Śiva).
By emphasizing bīja and śakti within each akṣara, it implies Śiva-tattva as conscious power (cit-śakti) present in sound (śabda), where disciplined mantra reveals the Lord as Pati who loosens pāśa (bondage).
Mantra-vidhi with nyāsa and chandas-awareness—reciting with proper svara and placing syllabic energies—supporting Shaiva sādhanā and Pāśupata-oriented purification.
