Krishna's myth

Krishna literally means the Black, the Dark, alluding to the dark blue skin of the most famous and most revered avatars of Vishnu.
Krishna was born in Mathura.
His father was the prince Vasudeva of Mathura and his mother the princess Devaki. The legend says that he was born from one of Vishnu’s hair. Kamsa, Devaki's brother who was king of Kashi was a sovereign cruel and immoral. He lived in constant fear that the childrens of his sister would take over the throne. So, he killed six successive children of Devaki and he emprisonned his sister with her husband.
Since his birth, the little Krishna was removed from the murderous wrath of his uncle. He grew among adoptive parents, Nanda and his wife Yashoda living retired in the Forest of Mahavena. A demon named Putna reached the home of Nanda with the appearance of a woman, she killed infants by coating her breasts with poison. Charmed by her beauty, Yashoda allowed Putna to nurse Krishna. Placed against the chest of the demon, Krishna began to suckle. Rather than swallowing the poison it’s the demon’s life that Krishna aspired. Yashoda found the child unharmed, he had killed Putna.
Throughout his childhood, Krishna was already reported by many miracles. The evil uncle, Kamsa continued to fight against Krishna. This one even managed to take over on Indra, whose anger against the inhabitants of a village was manifested by a terrible flood. To bring relief to residents, Krishna merely raised the whole town and the hill of Govardhana above his head.
