Ô brāhmanes, tigres parmi les deux-fois-nés : pour chaque Œuf cosmique (aṇḍa), Maheśvara, le grand Mahādeva, est la cause même. Il pénètre ce qui est dans l’Œuf, ce qui est hors de l’Œuf, et jusqu’aux enveloppes qui l’entourent.
Suta Goswami
It grounds Linga worship in Shaiva metaphysics: the Linga signifies Maheshvara as the causal and all-pervading Pati—present within the cosmos, beyond it, and in its subtle coverings—so worship is directed to the Lord who transcends yet indwells all.
Shiva-tattva is presented as both nimitta and upādāna in theistic Shaiva framing: Maheshvara is the abiding cause and pervader of every brahmāṇḍa, including its interior, exterior, and the limiting sheaths—showing transcendence (beyond) and immanence (within).
The verse supports Pashupata-oriented contemplation (bhāvanā) of Shiva’s vyāpti (all-pervasion): in puja and japa, the sādhaka meditates on Mahadeva as present in all loci—inner, outer, and subtle boundaries—loosening pasha (bondage) by aligning the pashu (soul) to Pati.
