Kurma Avatar: The Tortoise of Vishnu and the Churning of the Ocean

Kurma, “the tortoise”, is the second avatar of Vishnu in the list of the Dashavatara. His story is the heart of one of the best-loved episodes in Hindu tradition, the churning of the ocean of milk, known as Samudra Manthan. Gods and demons pull on either end of a great serpent, a mountain spins in the sea, treasures rise from the water, and Vishnu in the form of a tortoise holds the whole thing steady. This page tells the story, looks at what the texts say, and explains the day Kurma is remembered and the temples that honour him.

Where the story comes from

The churning of the ocean is told in the Mahabharata, in its first book, and in the Vishnu Purana, the Bhagavata Purana (in the eighth book) and several other Puranas. The Kurma Purana, one of the eighteen major Puranas, is named for the avatar, though its contents are mostly about Shiva, Vishnu and the duties of life, not only the tortoise story. Older Vedic texts also connect a tortoise with creation and with the foundation of the world, and scholars discuss how that older image was taken into the avatar story. The versions differ in small details, such as the order in which the treasures appear.

The story as the tradition tells it

The gods, the devas, had lost their strength after a curse from the sage Durvasa, and the demons, the asuras, grew powerful. On Vishnu’s advice, the devas made a truce with the asuras to churn the ocean of milk together, since the churning would produce amrita, the nectar that gives life without end. They would share it, the devas were told, though Vishnu planned a different outcome.

They took Mount Mandara as the churning rod and the serpent Vasuki as the rope. The devas held one end and the asuras the other, and they pulled back and forth. But the mountain, with nothing to support it, began to sink into the sea. At that moment Vishnu took the form of a vast tortoise, dived to the bottom of the ocean and held the mountain on his shell. As the churning went on, the poison Halahala rose first and threatened to burn the worlds, and Shiva drank it and held it in his throat, which is why he is called Neelakantha, the blue-throated one. Then came many treasures: the divine cow Kamadhenu, the white horse Uchchaihshravas, the elephant Airavata, the Kaustubha jewel, the wish-granting tree, the apsaras, and Lakshmi, who chose Vishnu as her lord. At the end Dhanvantari, the physician of the gods, rose with the pot of amrita.

The story does not end there. The asuras seized the pot, and Vishnu took the form of the enchantress Mohini to win it back and give it to the devas. Many tellings treat Mohini as a separate avatar, and the Bhagavata Purana includes her in its longer list of forms.

How the story is read

Tradition offers it as a story about effort, patience and cooperation among very different parties, and about the idea that great things come with difficulty: the poison comes before the nectar. Devotional readers see the tortoise as the steady support under every effort, bearing the weight without being seen. Yoga traditions have drawn on the tortoise too, as an image of the senses drawn inwards. The Bhagavad Gita uses that image in chapter 2 when it speaks of withdrawing the senses like a tortoise drawing in its limbs, though it does not refer to the avatar by name.

Tradition places the Kurma avatar in the Satya Yuga, after Matsya and before Varaha.

The festival: Kurma Jayanti

Kurma Jayanti is kept on the full Moon day of Vaishakha, the same Purnima that is observed as Buddha Purnima in the Buddhist tradition and as a time of bathing and charity in many Hindu regions. The date follows the tithi in your region and calendar, so check your own calendar, and see the Purnima guide for how the full Moon day is fixed.

Devotees fast, bathe at dawn, and worship Vishnu with a small image or picture of a tortoise. Some keep a tortoise-shaped item at home, and families who follow the Vastu tradition sometimes place a tortoise figure in the house. It is a custom and not a requirement of the festival. Others read the story of the churning aloud. These practices are regional and vary from one family to another.

Temples

• Sri Kurmam, Srikakulam district, Andhra Pradesh: the most famous temple of the tortoise avatar, and one of very few in India where Vishnu is worshipped as Kurma. Inscriptions that scholars place in the medieval period mention the temple, and tradition holds that the shrine is much older.
• Other places: the Kurma form appears in the avatar panels of many Vishnu temples, in carvings along gateways and walls, so look for the tortoise when you visit an old Vishnu shrine.

Timings, entry rules and festival schedules change, so read the temple’s own notice before you go.

Reading and reciting

The Samudra Manthan is also the story behind the Kumbh Mela in the popular tradition: drops of amrita are said to have fallen at four places, which became the Kumbh sites. The Vishnu Sahasranama is the hymn most often recited for Vishnu, and the Achyutashtakam is a shorter one.

The next avatar

After Kurma the list moves to Varaha, the boar, who lifts the earth from the waters. Return to the Dashavatara overview for the full list.
