नन्दिकेश्वरशिवलिङ्गमाहात्म्यवर्णनम्
The Māhātmya of the Nandikeśvara Śiva-liṅga
ऋषय ऊचुः । कथं गंगा समायाता वैशाखे सप्तमीदिने । नर्मदायां विशेषेण सूतैतद्वर्णय प्रभो
ṛṣaya ūcuḥ | kathaṃ gaṃgā samāyātā vaiśākhe saptamīdine | narmadāyāṃ viśeṣeṇa sūtaitadvarṇaya prabho
رشیوں نے کہا—وَیشاکھ کے مہینے کی سَپتمی کو گنگا کیسے آئی، خصوصاً نَرمدا میں؟ اے سوتا پرَبھُو، ہمیں اس کا بیان کیجیے۔
The sages (ṛṣis) at Naimiṣāraṇya
Jyotirlinga: Oṃkāreśvara
Sthala Purana: The question targets the Narmadā region where Oṃkāra (Mandhātā island) is famed; the chapter-turn suggests a tīrtha-māhātmya explaining Gaṅgā’s special presence/manifestation at Narmadā on Vaiśākha Saptamī (a confluence-miracle motif common in Purāṇic tīrtha lore).
Significance: Bathing/ritual at Narmadā with Gaṅgā-tulya (or Gaṅgā-sannidhi) on the specified tithi is framed as exceptionally merit-giving; supports the idea of intensified tīrtha-phala on calendrically marked days.
It frames a sacred-tīrtha inquiry: the sages seek the hidden Shaiva reason why Gaṅgā’s sanctity manifests on a specific lunar day at Narmadā, implying that time (tithi) and place (tīrtha) become especially grace-filled when connected to Śiva’s sacred geography.
In the Koṭirudra Saṃhitā, tīrthas and rivers are typically introduced to magnify Jyotirliṅga pilgrimage and Saguna Śiva’s accessible grace; this question prepares the narrative that links a particular river-observance to Śiva’s manifested presence and the merit of liṅga-centered worship nearby.
The verse points toward a Vaiśākha Saptamī tīrtha-observance—especially bathing and devotional acts at Narmadā—performed with Śiva-smaraṇa (remembrance), mantra-japa (such as the Pañcākṣarī “Om Namaḥ Śivāya”), and offerings appropriate to a Śaiva pilgrimage context.
