पूर्वकल्पसमुद्भूताञ् छ्रुतवन्तो यथा पुरा पञ्चाक्षरप्रभावाच्च लोका वेदा महर्षयः
pūrvakalpasamudbhūtāñ chrutavanto yathā purā pañcākṣaraprabhāvācca lokā vedā maharṣayaḥ
Así como en tiempos antiguos los nacidos de un kalpa anterior llegaron a ser oyentes de la verdad sagrada, del mismo modo, por el poder del mantra de cinco sílabas (Pañcākṣara), los mundos, los Vedas y los grandes Ṛṣi se manifiestan y quedan establecidos.
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.
