Adhyaya 70: आदिसर्गः—महत्-अहङ्कार-तन्मात्रा-भूतसृष्टिः, ब्रह्माण्डावरणम्, प्रजासर्गः, त्रिमूर्ति-शैवाधिष्ठानम्
आपो नाराश् च सूनव इत्यपां नाम शुश्रुमः आपूर्य ताभिर् अयनं कृतवानात्मनो यतः
āpo nārāś ca sūnava ityapāṃ nāma śuśrumaḥ āpūrya tābhir ayanaṃ kṛtavānātmano yataḥ
Kami telah mendengar bahawa “Air” dinamai “anak-anak Nara”. Setelah memenuhi hamparan kosmos dengan air-air itu, Tuhan menjadikannya tempat persemayaman (ayana) bagi Diri-Nya; maka baginda dikenali sebagai Nārāyaṇa.
Suta Goswami (narrating Purāṇic etymology within the cosmogonic account)
It grounds Linga-pūjā in cosmogony: the primordial waters (āpaḥ) are the first field of manifestation, and water-offerings (jala, abhiṣeka) become a symbolic return of the tattvas to the Supreme—Pati—who supports and pervades them.
Though the verse names Nārāyaṇa via the waters-as-abode motif, the Shaiva reading places Shiva-tattva as the transcendent Pati who makes the elements His “ayana” without being bound by them—remaining sovereign over pasha (bondage) and the evolving cosmos.
Water as a purifier is implied: abhiṣeka (ritual bathing of the Liṅga) and ācamana-like inner purification align with Pāśupata discipline—cleansing pasha so the pashu (soul) can recollect the Pati.
