Srila Visvanatha Cakravarti Thakura explains that the fratricidal battle of the Yadu dynasty and the hunter's attack upon Lord Krishna are clearly activities of the Lord's internal potency for the purpose of fulfilling the Lord's pastime desires. According to the evidence, the quarrel among the members of the Yadu dynasty occurred at sunset; then the Lord sat down on the bank of the Sarasvati River. It is stated that a hunter then arrived with the intention of killing a deer, but it is highly unlikely -- when more than 560 million warriors had just been killed in a great uproarious battle and the place had been flooded with blood and strewn with corpses -- that a simple hunter would somehow come along trying to kill a deer. Since deer are by nature fearful and timid, how could any deer possibly be on the scene of such a huge battle, and how could a hunter calmly go about his business in the midst of such carnage? Therefore, the withdrawal of the Yadu dynasty and Lord Krishna's own disappearance from this earth were not material historical events; they were instead a display of the Lord's internal potency for the purpose of winding up His manifest pastimes on earth.
