वासिष्ठकथनम् (आदित्य–सोमवंशवर्णनम् तथा रुद्रसहस्रनाम-प्रशंसा)
सुराणां संस्थितिर्यस्यां पितॄणां च सदा स्थितिः इक्ष्वाकुज्येष्ठदायादो मध्यदेशम् अवाप्तवान्
surāṇāṃ saṃsthitiryasyāṃ pitṝṇāṃ ca sadā sthitiḥ ikṣvākujyeṣṭhadāyādo madhyadeśam avāptavān
That land in which the Devas have their established abode, and in which the Pitṛs ever remain—there the eldest heir of Ikṣvāku’s line attained and came to rule the Madhyadeśa.
Suta Goswami
It frames Madhyadeśa as a divinely charged region—favored by Devas and Pitṛs—making it a fit kṣetra for dharma, Śiva-pūjā, and the establishment of Liṅgas where worship bears swift fruit.
Indirectly, it reflects Śiva as Pati who upholds cosmic order: where divine beings and ancestors are sustained, dharma flourishes—an expression of Śiva’s governance over both visible and subtle realms.
Pitṛ-kārya (ancestral offerings such as tarpaṇa and śrāddha) is implied; in Śaiva Siddhānta this supports the pashu (soul) by reducing pasha (bondage) through dharmic merit, complementing Śiva-pūjā rather than replacing it.
