Kurma Jayanti is celebrated all over India to worship Kurma, the second incarnation of the Hindu god Vishnu. Like most of the avatars of the Hindu god Vishnu, Kurma was a humanoid as well; he was half human and half tortoise. Kurma is a very important part of Hinduism as he depicts life.
According to Hindu mythology, Lord Vishnu took the form of Kurma to help the Gods in their war against the Demons. Once, the gods lost all of their strength due to a curse. They then decided to churn the ocean of milk after putting medicines in it so as to achieve nectar of immortality. Since, the gods could not do this alone; they asked the help of the demons, promising them a share of the nectar in return. Even with the joint strength of the demons, the churning proved to be too difficult and at this point Kurma appeared to help them, by lifting the churning stick on his back.
Kurma is celebrated in India as a symbol of life due to how he saved the gods and helped in the creation of immortality. Many fast on this day to receive blessings of Kurma for a long and prosperous life.
