Lord Krisna, the 10th incarnation  of  Lord Vishnu, took birth on earth with a purpose. The main objective of taking  human form by the divine being was to rid mother Earth from the cruelties and increasing power of the demons.

Life Span of Lord Krisna

It is believed that Bhagwan Krisna lived on Earth with brother Balram for 125 years. The first ten years of his life were spent in the towns of Gokul and Vrindavan, in Northern India. The following years beginning in the 11th year of Lord's life till the age of 28 were spent in Mathura. Sri Krisna later established Dwarka, a city in Gujarat and lived the rest of his life there with his wife Rukmini and sons.

Curse of Sages Vishwamitra and Narada

According to a folklore, Sage Vishwamitra and Sage Narada once visited the city of Dwarka to meet Lord Krisna. A few children of Lord Krisna dressed up Samba (Son of Sri Krisna and Jambavati) as a pregnant woman and asked the visiting sages to foretell what kind of a child Samba will bear. Feeling insulted, the sages cursed that Samba will give birth to an Iron rod which in turn will be instrumental in the fall of the Yaduvanshi Dynasty. The very next day, Samba gave birth to an iron rod. Lord Krisna's sons crushed it into powder and threw the bottle in the sea. However, one day the bottle was washed up the shore and the powdered iron took form of an arrow. Lord Krisna could foresee everything and as a last resort to save his Dynasty, prohibited liquor in the city of Dwarka. Eventually, the Yadavas became drunk and killed each other with iron rods. None of them survived. Lord Krisna was shattered to see the Dynasty perish.
