उमामहेश्वरव्रतं—पञ्चाक्षरमन्त्रस्य माहात्म्यं, न्यासः, जपविधिः, सदाचारः, विनियोगः
पूर्वकल्पसमुद्भूताञ् छ्रुतवन्तो यथा पुरा पञ्चाक्षरप्रभावाच्च लोका वेदा महर्षयः
pūrvakalpasamudbhūtāñ chrutavanto yathā purā pañcākṣaraprabhāvācca lokā vedā maharṣayaḥ
Sebagaimana pada masa silam mereka yang lahir dari kalpa terdahulu menjadi para pendengar kebenaran śruti, demikian pula oleh daya mantra Pañcākṣara, loka-loka, Weda, dan para Maharsi termanifestasi dan tegak berdiri.
Suta Goswami (narrating the Linga Purana to the sages of Naimisharanya)
It grounds Linga-worship in mantra-tattva: the Pañcākṣara (“namaḥ śivāya”) is presented as a creative and sustaining śakti through which sacred revelation and the cosmic order are established—hence it is central to Linga-pūjā.
Shiva as Pati is implied as the source of mantra-śakti: through His five-syllabled form, the Vedas (śruti), ṛṣis (seers), and lokas arise—indicating Shiva-tattva as the foundational consciousness-power behind manifestation.
Japa of the Pañcākṣara is highlighted as the core practice; in Shaiva Siddhanta/Pāśupata framing, mantra-japa purifies the paśu (soul), loosens pāśa (bondage), and orients the aspirant toward Pati (Shiva) during Linga-pūjā and meditation.
