That was the legend but science proved it partially. Scientists researched on that and have found some facts.Dwarka is derived from 'Dwar', a door, and in ancient times its flourishing port was considered to be the gateway to the main land. As 'Ka' means 'Brahma' meaning, gateway to Moksha. It is called Dwarkamati and Dwarkavati.
