The Vishweshwara-saṃhitā is a celebrated section of the Śiva Purāṇa, a medieval Śaiva scripture compiled and reworked over centuries. Framed around Śiva as Viśveśvara—"Lord of the Universe" and the presiding deity of Kashi—it weaves cosmology, mythic narratives, temple lore and ritual manuals. Key themes include Śiva’s role in creation and dissolution, the power of mantra and sacred places, bhakti and ascetic discipline, ethical conduct, and the promise of mokṣa. Rich in devotional episodes and practical guidance for worship and pilgrimage, the Saṃhitā has shaped temple ritual and popular devotion. Today it remains a living source for worship, pilgrimage traditions, theological reflection, and the cultural heritage of Hindu religious life.
