Krishna was born to destroy evil and establish peace on earth, with his uncle Kansa being the first one in line.

 

The story of Lord Krishna's birth is full of celestial occurrences that's so overwhelming that it generates the same amount of excitement every time you listen to it. Krishna was born to destroy evil and establish peace on earth, with his uncle Kansa being the first one in line. The king of Mathura, Kansa, was a cruel ruler who put his father Ugrasena, in jail. While he was marrying his sister off, an Akashvani (a divine voice) announced that Kansa's end was night and that he would be killed at the hands of Devki's 8th child, who would bring the rule of righteousness to the land.

A frightened Kansa put his sister and her husband in jail, vowing to kill every child she gave birth to. When Devki was due with her 8th child, the fear of having their newborn killed gripped the couple again. In the month of Bhadrapad, on the 8th day (Ashtami) of the Krishna Paksha (dark fortnight), Devki went into labour and gave birth to a boy. That night, all the prison guards fell asleep and Vasudev's shackles broke open on their own. And a divine voice asked Vasudev to carry the newborn to Nand Gaon, and trade him with the daughter of Nand Baba and Yashoda, who later turns out to be a form of Shakti, whom Kansa is unable to kill.

When Vasudev was crossing the overflowing Yamuna river, carrying his newborn in a basket, a heavy downpour began. It was then that Sheshnaag, the five-headed snake, which is also the bed of Lord Vishnu, spread his head to protect little Krishna from the rains.

This is not the only connection that Krishna has with the rains. At a very young age, he lifted an entire hill for villagers to take shelter and saved them from drowning. Krishna seems to have a strange connection with rain. It most definitely rains on Janmashtami.
