King Kansa, the evil uncle of Krishna, deputed demoness Putana to kill all the newborn babies in the village of Gokul. He was scared of his life, as the eighth son of Devaki and Vasudeva was prophecised to be his assassin. He came to know that his nemesis was already born and wanted to kill all the infants to avoid any risks.
Putana filled her breasts with poison and entered the village in the disguise of a beautiful woman. She started killing all the babies one by one by feeding milk from her poisoned breasts. She reached the palace of Nanda and Yashoda, Krishna’s foster parents. Nobody suspected any foul play thanks to her royal appearance. Putana approached the couch of the baby, carried him up in her arms and took him for feeding. Infant Krishna could discern the evil intention of the witch. He powerfully sucked her nipple and supped up the life out of her. The demoness was in terrible pain and her true personality was revealed. She fell lifeless on the ground stretching twelve miles across the site.
It is believed that Putana’s soul accomplished liberation as she committed the benign act of feeding her breast milk to Lord Krishna. Putana, like Yashodha, is also considered as a foster-mother of Krishna.
