Adhyaya 70: आदिसर्गः—महत्-अहङ्कार-तन्मात्रा-भूतसृष्टिः, ब्रह्माण्डावरणम्, प्रजासर्गः, त्रिमूर्ति-शैवाधिष्ठानम्
मन्वन्तरेण चैकेन सर्वाण्येवान्तराणि च कथितानि भविष्यन्ति कल्पः कल्पेन चैव हि
manvantareṇa caikena sarvāṇyevāntarāṇi ca kathitāni bhaviṣyanti kalpaḥ kalpena caiva hi
मन्वन्तरैककथने सर्वाण्यन्तराण्यपि सूचितानि । कल्पैककथने चैव कल्पस्वरूपं प्रकाशते; एवं पतेः शिवस्य लयतालाधिपतेः कालचक्रं पुनरावर्तते ॥

It frames Linga worship within recurring cosmic cycles (Kalpas and Manvantaras), implying that devotion to Pati (Śiva) remains the stable refuge for the Pashu (soul) across all repeating creations.
By emphasizing repeatable cosmic order, it points to Śiva as Pati—the steady Lord who transcends yet regulates time, while worlds and ages arise and dissolve in patterned succession.
No specific rite is named; the practical takeaway is to align pūjā and vrata with sacred time (tithi, yuga, kalpa awareness), a common Purāṇic discipline supporting Pāśupata orientation toward liberation.
