Adhyaya 70: आदिसर्गः—महत्-अहङ्कार-तन्मात्रा-भूतसृष्टिः, ब्रह्माण्डावरणम्, प्रजासर्गः, त्रिमूर्ति-शैवाधिष्ठानम्
किंनु रूपमहं कृत्वा उद्धरेयं महीमिमाम् जलक्रीडानुसदृशं वाराहं रूपमाविशत्
kiṃnu rūpamahaṃ kṛtvā uddhareyaṃ mahīmimām jalakrīḍānusadṛśaṃ vārāhaṃ rūpamāviśat
«In welcher Gestalt soll ich diese Erde emporheben?»—so erwog er und ging in die Gestalt Varāhas ein, des Ebers, der zum Spiel in den Wassern taugt, um sie emporzuheben.
Suta Goswami (narrating the Purana; describing the internal resolve of Vishnu/Varaha)
It frames cosmic restoration as a divinely assumed form and function; in Shaiva reading, such world-supporting acts occur under Pati’s sovereign order, which Linga worship honors as the stabilizing axis of creation.
Though the episode names Varaha, the theological backdrop in the Linga Purana emphasizes Pati (Shiva) as the supreme regulator of srishti-sthiti-pralaya; the capacity for forms and cosmic rescue is ultimately grounded in that supreme lordship.
A direct ritual is not stated; the takeaway aligns with Pashupata discipline—recognizing the Lord’s mastery over forms and elements, cultivating surrender (śaraṇāgati) and steadiness of mind amid cosmic upheaval.
