One night Krishna and Balarama are in the forest with the cowgirls when a yaksha demon, Sankhasura, a jewel flashing in his head, comes among them. He drives the cowgirls off but hearing their cries, Krishna follows after. Balarama stays with the girls while Krishna catches and beheads the demon.
On another occasion, Krishna and Balarama are returning at evening with the cows when a bull demon careers amongst them. He runs amok scattering the cattle in all directions. Krishna, however, is not at all daunted and after wrestling with the bull, catches its horns and breaks its neck.
To such blind attacks there is no immediate end. One day, however, a sage discloses to Kansa the true identity of his enemy. He tells him in what manner Balarama and Krishna were born, how Balarama was transferred from Devaki's womb to that of Rohini, and how Krishna was transported to Nanda's house in Gokula. Kansa is now confronted with the ghastly truth—how Vasudeva's willingness to surrender his first six sons has lulled his suspicions, how his confidence in Vasudeva has been entirely misplaced, and how completely he has been deceived. He sends for Vasudeva and is on the point of killing him when the sage interposes, advising Kansa to imprison Vasudeva for the present and meanwhile make an all-out attempt to kill or capture Balarama and Krishna. Kansa sees the force of his remarks, spares Vasudeva for the moment, throws him and Devaki into jail and dispatches a special demon, the horse Kesi, on a murderous errand.
As the horse speeds on its way, Kansa assembles his demon councillors, explains the situation to them and asks for their advice. If Krishna should not be killed in the forest, the only alternative, the demons suggest, is to decoy him to Mathura. Let a handsome theatre be built, a sacrifice to Siva held and a special festival of arms proclaimed. All the cowherds will naturally come to see it. Nanda, the rich herdsman, will bring presents, Krishna and Balarama will come with other cowherds. When they have arrived the wrestler Chanura can throw them down and kill them. Kansa is delighted at the suggestion, adding only that a savage elephant should be stationed at the gate ready to tear Krishna and Balarama to pieces immediately they enter. He then dismisses his demon advisers and sends for Akrura, the chief of the Yadavas and a leading member of his court. Akrura, he judges, will be the best person to decoy Krishna to Mathura. He accordingly briefs him as to his intentions and instructs him to await orders. Akrura deems it politic to express compliance but secretly is overjoyed that he will thus obtain access to the Krishna he adores.
The first stage of Kansa's master plan is now brought into effect. The horse demon, Kesi, reaches Brindaban and begins to paw the ground and kick up its heels. The cowherds are frightened but Krishna dares it to attack. The horse tries to bite him but Krishna plunges his hand down its throat and expands it to a vast size until the demon bursts. Its remains litter the ground but Krishna is so unmoved that he merely summons the cowherd children to play a game. Squatting with them under a fig tree, he names one of them a general, another a minister, a third a councillor and himself pretending to be a raja plays with them at being king. A little later they join him in a game of blind man's buff.
This unexpected dénouement enrages Kansa but instead of desisting from the attempt and bringing into force the second part of his plan, he decides to make one further effort to murder his hated foe. He accordingly summons the wolf demon, Vyamasura, gives him detailed instructions and dispatches him to Brindaban. The demon hies to the forest, arriving while Krishna and the children are still at blind man's buff. He has dressed himself as a beggar and going humbly up to Krishna asks if he may join in. Krishna tells him to choose whatever game he likes and the demon says, 'What about the game of wolf and rams?' 'Very well,' Krishna answers, 'You be the wolf and the cowherd boys the rams.' They start to play and the demon rounds up all the children and keeps them in a cave. Then, assuming true wolf's form he pounces on Krishna. Krishna, however, is quite prepared and seizing the wolf by the throat, strangles it to death.
Akrura is now sent for and instructed to go to Brindaban and return with Krishna to Mathura. He sets out and as he journeys allows his thoughts to dwell on the approaching meeting. 'Now,' he muses 'has my life borne fruit; my night is followed by the dawn of day; since I shall see the countenance of Vishnu, whose eyes are like the expanded leaf of the lotus. I shall behold that lotus-eyed aspect of Vishnu, which, when seen only in imagination, takes away the sins of men. I shall today behold that glory of glories, the mouth of Vishnu, whence proceeded the Vedas, and all their dependent sciences. I shall see the sovereign of the world, by whom the world is sustained; who is worshipped as the best of males, as the male sacrifice in sacrificial rites. I shall see Vishnu, who is without beginning or end; by worshipping whom with a hundred sacrifices, Indra obtained the sovereignty over the gods. The soul of all, the knower of all, he who is all and is present in all, he who is permanent, undecaying, all-pervading will converse with me. He, the unborn, who has preserved the world in the various forms of a fish, tortoise, a boar, a horse, a lion will this day speak to me. Now the lord of the earth, who assumes shapes at will, has taken upon him the condition of humanity, to accomplish some object cherished in his heart. Glory to that being whose deceptive adoption of father, son, brother, friend, mother, and relative, the world is unable to penetrate. May he in whom cause and effect, and the world itself, is comprehended, be propitious to me, through his truth; for always do I put my trust in that unborn, eternal Vishnu; by meditation on whom man becomes the repository of all good things.'[31]
He goes on to think of how he will kneel before Krishna with folded hands and afterwards put on his head the dust of Krishna's feet—the same feet which 'have come to destroy crime, which fell on the snake Kaliya's head and which have danced with the cowgirls in the forest.' Krishna, he believes, will know at once that he is not Kansa's envoy and will receive him with kindness. And this is what actually ensues. Meeting Krishna outside Brindaban, he falls at his feet, Krishna lifts him up, embraces him and brings him into Nanda's house. Akrura tells Nanda and Krishna how Kansa has oppressed the people of Mathura, imprisoned Vasudeva and Devaki and has now sent him to invite them to attend the festival of arms. Krishna listens and at once agrees to go, while Nanda sends out a town-crier to announce by beat of drum that all the cowherds should get ready to leave the next day. When morning comes, Krishna leaves in a chariot, accompanied by the cowherds and their children.
The news of his sudden departure devastates the cowgirls. Since the circular dance in which their love was consummated, they have been meeting Krishna every evening and delighting in his company. And during the daytime their passionate longings have centred solely on him. That he should leave them so abruptly causes them complete dismay and they are only comforted when Krishna assures them that he will return after a few days.
On the way to Mathura Akrura bathes in the Jumna and is granted a vision of Krishna as Vishnu himself.
