Chapter 8
Krishna
This avatar knew who he was — and that is the whole difference
The third birth
The curse of Jaya and Vijaya runs through three births.
First they appear as Hiranyaksha and Hiranyakashipu, whose stories belong to Varaha and Narasimha.
Then as Ravana and Kumbhakarna in the Ramayana.
Their third and final birth is as Shishupala and Dantavakra, in Krishna's time.
So a thread that began several chapters ago closes here.
The same shape, again
Krishna's own story begins in Mathura with a ruler who has been warned about the manner of his death.
Kamsa responds as rulers in these stories often do: he tries to seal every route by which the prediction might come true. He imprisons, counts births and watches the same door again and again.
And, as so often happens in these stories, the attempt to prevent the prophecy becomes part of the path by which it is fulfilled.
What is different
But Krishna differs sharply from Rama.
Rama does not stand within his own story and declare who he is. Krishna does.
On the battlefield of Kurukshetra, he tells Arjuna directly, and that conversation becomes the Bhagavad Gita, standing apart within the Mahabharata.
This is why Krishna is read differently from the earlier avatars: here, the figure inside the story speaks openly about his own divine identity.
Where the rest of the story is
His childhood in Gokul, Kaliya, Govardhan, Mathura and Dwarka belongs to the Krishna-Leela section of this site.
Kurukshetra belongs to the Mahabharata.
This chapter does not repeat those stories. Its purpose is simply to place Krishna within the larger sequence.
Note: Krishna is counted eighth among the ten avatars, and his whole story is on this site separately in Krishna-Leela — so this chapter does not repeat it. The fifth amsha of the Vishnu Purana is entirely Krishna's story. The difference worth noticing is that the Mahabharata has no childhood for Krishna; that comes in the Harivamsha and the tenth skandha of the Bhagavata Purana, which is to say in a later layer. The three-birth frame of Jaya and Vijaya is the Bhagavata's. The greatest variation in the Dashavatara list is at the ninth place, where some lists have Balarama in Buddha's stead.
