Since Kamsa was now dead, it was time for Krishna and Balarama to go to their guru’s house for studying. Their guru was a sage named Sandipani, who lived in Kashi. There Krishna and Balarama went to learn amongst other things, the art of fighting. It took them only sixty-four days to learn all this. After the shishya’s studies are completed he had to give a dakshina to his guru. Sandipani’s son had died and as guru dakshina, Sandipani desired that his dead son might be brought back to life.

After death, the sage Sandipani’s son had gone to the great ocean. Krishna and Balarama took up their weapons and went to the ocean to demand the son. The ocean told them that the son was actually with a daitya named Panchajana who had the form of a conch-shell. Krishna entered the ocean and killed it. From the skeleton of the daitya was made the conch-shell Panchajanya that Krishna blows. To get back the dead son, Krishna and Balarama also had to go to Yama’s world and defeat Yama. They did that and returned the son to the sage Sandipani.

They then returned to Mathura.
