After the Mahabharata war, the Pandavas received their kingdom and dharma was established. But Gandhari, grief-stricken over her sons, cursed Shri Krishna that the Yadava clan would perish, and the Lord calmly accepted it.
In time, through the curse of sages and quarrels among themselves, the Yadavas met their end at Prabhas. Balarama left his body on the seashore.
After this, Shri Krishna was sitting in meditation beneath a pipal tree near Prabhas Patan (Somnath). A hunter named Jara, seeing his foot from afar, mistook it for a deer and shot an arrow. When he realised his mistake he began to weep, and the Lord forgave him. This holy place is known today as Bhalka Tirth.
From there Shri Krishna returned to his own abode, Vaikuntha, and according to tradition the age of Kali Yuga began from that time. His divine play, the teaching of the Gita and the path of devotion still live on in the hearts of millions of devotees today.
