सृष्ट्यर्थं संस्थितं वह्निं संक्षिप्य च हृदि स्थितम् ध्यात्वा यथावद्देवेशं रुद्रं भुवननायकम्
sṛṣṭyarthaṃ saṃsthitaṃ vahniṃ saṃkṣipya ca hṛdi sthitam dhyātvā yathāvaddeveśaṃ rudraṃ bhuvananāyakam
Having drawn inward the sacred fire established for creation and set it within the heart, one should meditate in the proper manner upon Rudra—the Lord of the gods, the sovereign guide of all the worlds—who is Pati, the inner ruler who frees the paśu from pāśa through right contemplation.
Suta Goswami (narrating the Purva-Bhaga teachings to the sages of Naimisharanya)
It shifts worship from only external rite to inner upāsanā: the sacrificial fire (vahni) is internalized into the heart, and Rudra is contemplated there as the true Linga-principle (the inner sign of Pati).
Shiva is presented as Deveśa and Bhuvananāyaka—supreme Lord and cosmic ruler—realized through correct dhyāna; he is Pati who governs creation and releases the bound soul (paśu) from bondage (pāśa) by inner realization.
A Pāśupata-style contemplative practice: pratyāhāra-like withdrawal of the ritual fire into the heart (antar-agni) followed by rule-based meditation (yathāvat-dhyāna) on Rudra.
