Adhyaya 23: श्वेत-लोहित-पीत-कृष्ण-विश्व-कल्पेषु रुद्रस्वरूप-गायत्री-तत्त्ववर्णनम्
अजश्चैव महातेजा विश्वरूपो भविष्यति अमोघरेताः सर्वत्र मुखे चास्य हुताशनः
ajaścaiva mahātejā viśvarūpo bhaviṣyati amogharetāḥ sarvatra mukhe cāsya hutāśanaḥ
He is indeed Unborn (Aja), of immense splendor, and will become the Cosmic-Formed One (Viśvarūpa). His generative power is unfailing; and in every direction, in his very mouths, Hutāśana—the Fire-god—abides, signifying the Lord as Pati who consumes and transforms all, sustaining creation through sacred fire.
Suta Goswami (narrating Purāṇic description to the sages of Naimiṣāraṇya, preserving an older dialogue on the Lord’s cosmic marks)
It frames the Linga’s Lord as aja (unborn) and viśvarūpa (all-pervading), so worship is not of a limited deity but of Pati—the transcendent-immanent Shiva—present even in sacrificial fire (Agni) and thus in all Vedic and Shaiva rites.
Shiva-tattva is shown as unborn radiance (mahātejas) with cosmic embodiment (viśvarūpa) and inexhaustible creative power (amogharetas), indicating the Lord’s sovereignty over sṛṣṭi while remaining unconditioned by it—Pati distinct from pashu and pasha.
The verse points to Agni-centered worship—homa and inner-fire contemplation—where outer hutāśana mirrors the yogic fire that burns pasha (bondage), aligning with Pāśupata discipline of purification and transformation.
