Adhyaya 4: अहोरात्र-युग-मन्वन्तर-कल्पमान तथा प्रलयान्ते सृष्ट्युपक्रमः
भवोद्भवस्तपश्चैव भव्यो रम्भः क्रतुः पुनः ऋतुर्वह्निर्हव्यवाहः सावित्रः शुद्ध एव च
bhavodbhavastapaścaiva bhavyo rambhaḥ kratuḥ punaḥ ṛturvahnirhavyavāhaḥ sāvitraḥ śuddha eva ca
He is Bhavodbhava, the source from whom becoming itself arises; He is Tapas, the power of ascetic heat. He is Bhavya, the auspicious and beneficent One; Rambha, the delightful Presence. He is Kratu, the very form of Vedic sacrifice; He is Ṛtu, the ordered rhythm of the seasons. He is Vahni, the sacred Fire, and Havyavāha, the bearer of oblations; He is Sāvitra, the divine inspirer of the intellect; and He alone is Śuddha, ever-pure, untouched by pāśa (bondage).
Suta Goswami (narrating Shiva’s names to the sages of Naimisharanya)
This verse presents Shiva as the inner reality of yajña (Kratu) and the sacred fire that carries offerings (Havyavāha), teaching that Linga-puja is not separate from Vedic worship—its essence is offering the self (pashu) into the awareness of Pati, the ever-pure Śiva.
Shiva-tattva is shown as both immanent and transcendent: immanent as time’s order (Ṛtu) and ritual fire (Vahni), transcendent as Śuddha—pure consciousness untouched by pāśa, the bonds that limit the pashu (individual soul).
Tapas is highlighted as the yogic discipline that burns impurities, while the yajña-idea (Kratu, Havyavāha) points to a Shaiva inward sacrifice—offering breath, mind, and actions into Shiva through mantra and Linga-puja.
