The body text this entry carried previously described the one hundred and eight Divya Deśams and then named Dwarakādhiśa — the principal deity of the Dwarka temple. Neither of those is the subject of this entry, and the text belonged, if anywhere, to a general Tamil Vaiṣṇava entry. It has been replaced. What follows is about Kalyāna-Nārāyaṇa in Dwarka, and where the naming is uncertain we say so.
Kalyāna-Nārāyaṇa is, in and around Dwarka, not a separate god but a name and a set of festivities for Krishna as the joyful bridegroom — kalyāna, "the wedding", is the central word. Devotees use it in at least two senses, and the two should not be run together: as a name for the deity worshipped at the town, and as a description of the annual marriage rite performed there. The principal shrine of Dwarka is commonly called the Dwarkādhiśa temple, and its deity is also referred to locally as Kalyāna-Nārāyaṇa Swāmi. A guardian should establish, from Gujarati and Devanagari sources, whether the entry is meant to record the deity, the festival, or both — and if so, split it.
Dwarka in Devbhumi Dwarka district of Gujarat is one of the four sapta-purī of the Vaiṣṇava list, and one of the principal centres of the Bhāgavata cult: the Bhāgavata Purāṇa itself is understood in the region to have been revealed at Dwarka, and a Bhāgavata library and its associated learned institutions are the region's standing intellectual apparatus. This is a Śvetāṅgara or Vaiṣṇava āgama establishment, not merely a pilgrimage town, and the distinction matters for how the deity is served — by a Bābā or Śāstrī learned in the Bhāgavata, with a textual and philosophical discipline of its own.
The town's shrines are several and distinct: the principal Dwarkādhiśa temple; shrines associated with Rukmini, Rādhā-Krishna and Gopāla; the Hanumān shrine; and in the wider district, the Nageshvara Jyotirlinga and a set of sites associated with Krishna's infancy and his departure for the south. They are not interchangeable, and the district's pilgrimage routes differ from the town's temple sequence.
The festival this entry most plausibly names is the annual marriage rite in which Krishna is wed to Rukmini, observed with processions, a full śṛṅgāra programme of music and dance, and the svarṇapuṣpa and grih praveśa sequence of the wedding day. The date follows the regional lunar calendar, and the observance is shared across the Vaiṣṇava communities of Gujarat with variations in date and in procession route.
We do not hold a source that fixes the present temple buildings to a date, that establishes which office holds the image, or that documents the modern administration. The c. 15th-century association sometimes given for the main temple should be treated as a tradition claim. Dwarka's history includes periods when the shrine was not under Hindu administration, and a continuous institutional history cannot be assumed across them.
The Vaiṣṇava frame — sapta-purī, the Bhāgavata as revealed at Dwarka, the Śvetāṅgara institutional form — should be read against standard scholarship on the Vaiṣṇava āgamas and against the district gazetteer. The Bhāgavata Purāṇa is the tradition's own scripture and is cited here at that level, not by verse. The open questions above all need Gujarati sources.
