हंस-वराह-रूपग्रहण-कारणम्
The Reason for Assuming the Swan and Boar Forms
सहस्रशीर्षा पुरुषस्सहस्राक्षः सहस्रपात् । स भूमिं सर्वतस्पृत्वा तदण्डं व्याप्तवानिति
sahasraśīrṣā puruṣassahasrākṣaḥ sahasrapāt | sa bhūmiṃ sarvataspṛtvā tadaṇḍaṃ vyāptavāniti
That Cosmic Person—of a thousand heads, a thousand eyes, and a thousand feet—pervaded the earth on every side; touching it all around, he completely filled and encompassed that cosmic Egg, the universe.

Tattva Level: pati
Shiva Form: Tatpuruṣa
Type: rudram
Role: nurturing
Cosmic Event: vyāpti (cosmic pervasion) of the puruṣa within the brahmāṇḍa
It points to the Supreme Lord (understood in Shaiva Siddhanta as Shiva, the Pati) as the all-pervading consciousness that contains and sustains the entire brahmāṇḍa; contemplating this dissolves the sense of separateness and turns the mind toward liberation.
The verse describes Shiva’s cosmic pervasion (a Saguna pointer to the Nirguna reality). Linga-worship trains the devotee to see the one Lord present in every form—so the Linga becomes the focal symbol of the same all-encompassing Shiva who fills the universe.
A simple dhyāna is suggested: visualize Shiva as viśvavyāpaka (all-pervading) while repeating the Panchakshara—“Om Namaḥ Śivāya”—and offering bilva leaves or bhasma with the feeling that the entire universe is His body.
