सतीचरिते पितृगृहे आशीर्वाद-वचनम् तथा यौवनारम्भः — Satī at her father’s house: blessings and the onset of youth
आदिबीजाय सर्वेषां चिद्रूपाय पराय च । ब्रह्मणे निर्विकाराय प्रकृतेः पुरुषस्य च
ādibījāya sarveṣāṃ cidrūpāya parāya ca | brahmaṇe nirvikārāya prakṛteḥ puruṣasya ca
Salutations to Him who is the primal seed of all, whose very nature is pure Consciousness, who is the Supreme; to that Brahman—unchanging and without modification—who transcends both Prakṛti (Nature) and Puruṣa (the individual conscious principle).
Sūta Gosvāmin (narrating to the sages at Naimiṣāraṇya within the Rudrasaṃhitā, Satīkhaṇḍa context)
Tattva Level: pati
Shiva Form: Īśāna
It identifies Shiva as the primal cause and as pure Consciousness (cit), declaring Him the changeless Supreme who stands beyond the limiting categories of nature (prakṛti) and the individual soul-principle (puruṣa), guiding the seeker toward liberation through right understanding of Pati (the Lord).
The Liṅga is revered as the sign of the formless, changeless Brahman-Shiva described here; Saguna worship (form, mantra, ritual) is a supported means to approach and realize the Nirguna reality—Shiva as pure Consciousness beyond all modifications.
Meditate on Shiva as nirvikāra (unchanging) Consciousness while repeating the Pañcākṣarī “Om Namaḥ Śivāya,” and perform simple Liṅga-upāsanā (water/offerings) with the intent of realizing Shiva beyond prakṛti and ego-bound individuality.
