"After this, you know, comes the Maushala of painful incidents. In this, those lion-hearted heroes (of the race of Vrishni) with the scars of many a field on their bodies, oppressed with the curse of a Brahmana, while deprived of reason from drink, impelled by the fates, slew each other on the shores of the Salt Sea with the Eraka grass which (in their hands) became (invested with the fatal attributes of the) thunder. In this, both Balarama and Kesava (Krishna) after causing the extermination of their race, their hour having come, themselves did not rise superior to the sway of all-destroying Time. In this, Arjuna the foremost among men, going to Dwaravati (Dwaraka) and seeing the city destitute of the Vrishnis was much affected and became exceedingly sorry. Then after the funeral of his maternal uncle Vasudeva the foremost among the Yadus (Vrishnis), he saw the heroes of the Yadu race lying stretched in death on the spot where they had been drinking. He then caused the cremation of the bodies of the illustrious Krishna and Balarama and of the principal members of the Vrishni race. Then as he was journeying from Dwaraka with the women and children, the old and the decrepit--the remnants of the Yadu race--he was met on the way by a heavy calamity. He witnessed also the disgrace of his bow Gandiva and the unpropitiousness of his celestial weapons. Seeing all this, Arjuna became despondent and, pursuant to Vyasa's advice, went to Yudhishthira and solicited permission to adopt the Sannyasa mode of life. This is the sixteenth Parva called Maushala The number of sections is eight and the number of slokas composed by Vyasa cognisant of truth is three hundred and twenty.
