Akupara

Akupara is a legendary creature from Hindu myth. He is seen as the immortal king of all tortoises living in Lake Indradyumna in the Himalayas. The top of its shell holds the sky, and the flat bottom of the shell is the earth’s surface. Akupara dove to the bottom of the primordial ocean and supported the mountain the gods were using to churn it. He is known to have reorganized the reincarnated king Indradyumna in the Mahabharata.
