A summary of the Sixth Chapter is as follows: when Nanda Maharaja, following the instructions of Vasudeva, was returning home, he saw a great demoniac woman lying on the road, and then he heard about her death.
While Nanda Maharaja, the King of Vraja, was thinking about Vasudeva's words concerning disturbances in Gokula, he was a little afraid and sought shelter at the lotus feet of Sri Hari. Meanwhile, Kamsa sent to the village of Gokula a Rakshasi named Putana, who was wandering here and there killing small babies. Of course, wherever there is no Krishna consciousness, there is the danger of such Rakshasis, but since the Supreme Personality of Godhead Himself was in Gokula, Putana could accept nothing there but her own death.
One day, Putana arrived from outer space in Gokula, the home of Nanda Maharaja, and by displaying her mystic power, she assumed the disguise of a very beautiful woman. Taking courage, she immediately entered Krishna's bedroom without anyone's permission; by the grace of Krishna, no one forbade her to enter the house or the room, because that was Krishna's desire. The baby Krishna, who resembled a fire covered by ashes, looked upon Putana and thought that He would have to kill this demon, the beautiful woman. Enchanted by the influence of yogamaya and the Personality of Godhead, Putana took Krishna upon her lap, and neither Rohini nor Yasoda objected. The demon Putana offered her breast for Krishna to suck, but her breast was smeared with poison. The child Krishna, therefore, squeezed Putana's breast so severely that in unbearable pain she had to assume her original body and fell to the ground. Then Krishna began playing on her breast just like a small child. When Krishna was playing, the gopis were pacified and took the child away to their own laps. After this incident, the gopis took precautions because of the attack of the Rakshasi. Mother Yasoda gave the child her breast to suck and then laid Him in bed.
Meanwhile, Nanda and his associates the cowherd men returned from Mathura, and when they saw the great dead body of Putana, they were struck with wonder. Everyone was astonished that Vasudeva had foretold this mishap, and they praised Vasudeva for his power of foresight. The inhabitants of Vraja cut the gigantic body of Putana into pieces, but because Krishna had sucked her breast, she had been freed from all sins, and therefore when the cowherd men burned the pieces of her body in a fire, the smoke filled the air with a very pleasing fragrance. Ultimately, although Putana had desired to kill Krishna, she attained the Lord's abode. From this incident we gain the instruction that if one is attached to Krishna somehow or other, even as an enemy, one ultimately attains success. What then is to be said of devotees who are naturally attached to Krishna in love? When the inhabitants of Vraja heard about the killing of Putana and the welfare of the child, they were very much satisfied. Nanda Maharaja took the baby Krishna on his lap and was filled with satisfaction.
