Dwaravati

Dvaraka, also known as Dvāravatī (Sanskrit द्वारका "the many-gated [city]") is a sacred city in Hinduism, Jainism and Buddhism. The name Dvaraka is said to have been given to the place by Krishna, a major deity in Hinduism. Dvaraka is one of the Sapta Puri (seven sacred cities) of Hinduism.

In the Mahabharata, it was a city located in what is now Dwarka, formerly called Kushasthali, the fort of which had to be repaired by the Yadavas. In this epic, the city is described as a capital of the Anarta Kingdom. According to the Harivamsa the city was located in the region of the Sindhu Kingdom.

In the Hindu epics and the Vaishnava Puranas, Dvaraka is called Dvaravati and is one of seven Tirtha (pilgrimage) sites for spiritual liberation. The other six are Mathura, Ayodhya, Kashi, Kanchipuram, Avantika (Ujjain) and Puri.

The following description of Dvaraka during Krishna’s presence there appears in the Bhagavata Purana (Srimad-Bhagavatam; 10.69.1-12) in connection with the sage Narada’s visit.

The City was filled with the sounds of birds and bees flying about the parks and pleasure gardens, while its lakes, crowded with blooming indivara, ambhoja, kahlara, kumuda, and utpala lotuses, resounded with the calls of swans and cranes.

Dvaraka boasted 900,000 royal palaces, all constructed with crystal and silver and splendorously decorated with huge emeralds. Inside these palaces, the furnishings were bedecked with gold and jewels.
