Musala Parva describes how the great society of Yadavas at Drawaka were destroyed due to factional fighting. It is not sure if this was a conspiracy of the Gandharas. However the seeds of mis-trust was sown during the Kurukshetra War when Satyaki and Kritavarma both Yadavas, yet fought the war on opposing sides. It is not sure if the sinking of Dwaraka coincided with the destruction of the Yadava society. All of these could be many factors that contributed to the destruction. One possibility is that the society is destroyed and then the island sank subsequently. Another possibility is that the Dwaraka island sank and the people settled on the sea shore near to the island. In that chaos, a fight broke between Kritavarma and Satyaki, which flared into a full blown war between the Yadava clan. Krishna and his brother Rama could not prevent the collapse of the society. When Arjuna arrived from Hastinapura knowing about the calamity, he could only witness his beloved friend and cousin Krishna in his last moments seated in Yoga above a tree and could not do anything.
Arjuna witness Krishna, his beloved friend, guide and cousin, in his last moments seated in Yoga, and the island Dwaraka half sunk in the sea.
