Adhyaya 27
सर्वज्ञत्वं तथैशान्यं कर्णिका सोम उच्यते सोमस्याधस् तथा सूर्यस् तस्याधः पावकः स्वयम्
sarvajñatvaṃ tathaiśānyaṃ karṇikā soma ucyate somasyādhas tathā sūryas tasyādhaḥ pāvakaḥ svayam
Omniscience and the Iśāna (northeast, sovereign) principle are said to abide in the karṇikā, the central core; there Soma is declared to preside. Below Soma is Sūrya, and below him indeed is Pāvaka (Agni) himself.
Suta Goswami (narrating the Linga-maṇḍala symbolism within the Purāṇic discourse)
It assigns specific cosmic deities (Soma, Sūrya, Agni) to vertical positions in the Linga-lotus maṇḍala, guiding dhyāna and nyāsa so the worshipper aligns the ritual form with Śiva’s all-knowing Iśāna principle.
By locating sarvajñatva (omniscience) and the Iśāna-bhāva in the central karṇikā, it points to Śiva as Pati—the sovereign consciousness that orders and transcends the lower functional powers represented by Soma, Sūrya, and Agni.
Maṇḍala-dhyāna in Linga-pūjā: contemplating the karṇikā as Iśāna-sarvajña Śiva while placing Soma above, with Sūrya and Agni below, as an inner visualization to purify the pashu (soul) and loosen pāśa (bondage).
