The Janmashtami katha is the story of Krishna's birth: how Kamsa, king of Mathura, imprisoned his sister Devaki and her husband Vasudeva after a voice foretold that her eighth child would end his rule, and how Krishna was born to them in the prison at midnight and carried across the flooded Yamuna to safety in Gokul. It is told on the night of Krishna Paksha Ashtami, the eighth day of the waning moon, before the midnight puja.
The day, the Smarta and Vaishnava dates and the nishita kaal window for your city are on the Janmashtami date page. This page is only the story, told in our own words.
The story of Krishna's birth
The wedding and the voice from the sky
Ugrasena was the king of the Yadavas in Mathura, but his son Kamsa had taken the throne and put his own father in prison. Kamsa was fond of one person: his cousin Devaki. When she was married to the Yadava prince Vasudeva, Kamsa himself took the reins of the wedding chariot to drive the couple home.
On the way, a voice spoke from the sky. It told Kamsa that the eighth child of the girl he was driving with such care would be the cause of his death. Kamsa's affection vanished in an instant. He drew his sword and seized Devaki by the hair.
Vasudeva held his arm. He spoke calmly, reminding Kamsa that killing a bride on her wedding day would shame him for ever, and that Devaki herself was no danger to him. Then he made a promise: every child Devaki bore, he would hand over to Kamsa with his own hands. Kamsa knew Vasudeva never broke his word, and he lowered the sword.
The prison
To be sure, Kamsa had the couple locked in a prison in Mathura, with guards at every door. When their first son was born, Vasudeva kept his promise and brought the child to Kamsa. One after another, six children were born, and Kamsa took the lives of all six.
Reading this part calmly
This is the hardest part of the story, and families tell it briefly. The Bhagavata itself softens it: the six are said to have been souls carrying an old curse, released by their short birth, and in a later chapter Krishna brings them back to meet their mother. The story does not ask listeners to dwell on the cruelty; it shows how fear can make a person do terrible things, and sets up the night when that fear is finally outwitted.
The seventh child
When Devaki conceived a seventh time, Vishnu called on Yogamaya, his power of illusion. She drew the unborn child from Devaki's womb into that of Rohini, Vasudeva's other wife, who was living safely in Gokul under the protection of the cowherd chief Nanda. The prison was told that Devaki had lost the child. In Gokul, Rohini gave birth to a son, Balarama, also called Sankarshana, "the one who was drawn away".
The eighth child, at midnight
Then Devaki conceived for the eighth time, and the prison seemed to fill with light. Kamsa doubled the guards and chained the couple.
On the eighth day of the dark half of Bhadrapada, with the moon in Rohini nakshatra, at the middle of the night, the child was born. The stories say Vasudeva and Devaki first saw him as Vishnu, with four arms holding conch, discus, mace and lotus. They folded their hands, and at Devaki's request he became an ordinary newborn. He told Vasudeva what to do.
At once the guards fell into a deep sleep. The chains opened, and the heavy prison doors swung back on their own. Vasudeva laid the baby in a basket, put it on his head, and walked out into the night.
Across the Yamuna
Outside, rain was falling hard and the Yamuna was in flood. Vasudeva stepped in. The water rose to his chest, then to his chin. In the well-loved telling, the river rose to touch the baby's feet and then fell back; and the great serpent Shesha followed behind, spreading his many hoods over the basket like an umbrella so that not a drop fell on the child. The river parted to let them through.
In Gokul, Yashoda, Nanda's wife, had just given birth to a daughter, and the whole household was asleep. Vasudeva placed his son beside Yashoda, lifted the baby girl, and walked back through the river to the prison. The doors closed behind him, the chains fell back into place, and the girl began to cry.
Yogamaya's warning
The guards woke and ran to Kamsa. He came at once and snatched the baby from Devaki, who begged him to spare a daughter. Kamsa raised the child to strike her against a stone.
She slipped from his hands and rose into the sky. There she appeared as the goddess Yogamaya, shining and armed with eight weapons, and she spoke to him: the one who would end his rule had already been born, and was safe elsewhere. Then she vanished. In many tellings she is worshipped afterwards in many places, among them Vindhyavasini.
Kamsa, shaken, set Devaki and Vasudeva free and asked their forgiveness. But his fear soon returned, and the stories of Gokul, of the demons he sent after the child and of how each one failed, begin from here.
How the katha is heard
Families tell the story in the evening, as the night builds towards midnight. In many homes it is read in stages, so that the birth itself comes at nishita kaal: the doors open, the conch is blown, the cradle is rocked and a bell rings. Temples in Mathura and Vrindavan tell it through jhankis, scenes set up with small figures, and children often act out the crossing of the Yamuna with a basket and a toy snake.
The full order of the night, the samagri and the midnight abhishek are on the Janmashtami puja vidhi page.
Other tellings
- Nandotsav. The next morning in Gokul, Nanda wakes to find a son and throws open his house; the celebration of that morning is kept as Nandotsav, and in Maharashtra the following day is Gopalkala, the day of Dahi Handi.
- Other Puranas. The Harivamsha and the Vishnu Purana tell the same outline with small differences, for example in how Yogamaya is named and in what she says to Kamsa; vrat books usually follow the Bhagavata.
- South India calls the day Gokulashtami or Sri Jayanti, and tells the same story with the child's small footprints drawn at the door, walking in.
What the story carries today
At heart, Janmashtami is a story about a birth that fear could not stop. Locked doors, chains and a flooded river all give way to a newborn. For most families the night is less about Kamsa than about the baby: the cradle, the butter, the laughter of a child about to grow up in a village of cowherds.
Krishna's childhood continues in the Govardhan Puja story, when he lifts the hill to shelter Gokul. For the night itself, the panchang for your city shows when Ashtami begins, and the moonrise page gives the late-night moonrise many families watch for on this night.
