Adhyaya 70: आदिसर्गः—महत्-अहङ्कार-तन्मात्रा-भूतसृष्टिः, ब्रह्माण्डावरणम्, प्रजासर्गः, त्रिमूर्ति-शैवाधिष्ठानम्
तदाचलत्वाद् अचलाः पर्वभिः पर्वताः स्मृताः गिरयो हि निगीर्णत्वाच् छयानत्वाच्छिलोच्चयाः
tadācalatvād acalāḥ parvabhiḥ parvatāḥ smṛtāḥ girayo hi nigīrṇatvāc chayānatvācchiloccayāḥ
अचलपणामुळे ते ‘अचल’ म्हणतात. कडे-गाठी (पर्व) असल्यामुळे ते ‘पर्वत’ म्हणून स्मरणात आहेत. जणू गिळले गेले आहेत अशा घनत्वामुळे ते ‘गिरी’, आणि शिळांचा मोठा ढिगारा होऊन पसरल्यामुळे ‘शिलोच्चय’ म्हणतात.
Suta Goswami
It frames sacred geography: mountains as stable, rock-formed pillars of the manifest world, which supports the Shaiva view of the cosmos as a field where the Linga (Pati) is worshipped through stable, consecrated places.
By emphasizing immovability and steadfastness (acalatva), it indirectly mirrors Shiva-tattva as the unmoving Pati—unchanging consciousness—upon which changing creation is structured.
No specific rite is prescribed here; the takeaway is the Shaiva sacralization of mountains as ideal kshetras for tapas, dhyana, and Linga-sthapana within a Pashupata-oriented worldview.
