By these seven primordial (prākṛta) enclosures the cosmic egg (aṇḍa) is surrounded. Each of them, mutually covering the others in succession, stands established as the eightfold Prakṛti.
Suta Goswami (narrating the cosmological teaching within the Linga Purana discourse)
It frames the universe as layered by prākṛta coverings; in Linga worship, the devotee (pashu) symbolically pierces these layers through jñāna and pūjā, turning from Prakṛti to the transcendent Pati, Shiva.
By emphasizing that the cosmos is enclosed by Prakṛti’s layers, it implies Shiva-tattva as the unbounded reality beyond these coverings—Pati who is not confined by the eightfold Prakṛti and who grants release from pasha (bondage).
A tattva-oriented Pāśupata contemplation is suggested: meditating on successive coverings of Prakṛti and inwardly offering them into the Linga as a practice of dis-identification from pasha and reorientation to Shiva.
