The Mahabharata - pg. 302

At that moment, the other Pandavas also joined Arjuna, but the grandsire was able to hold his own against all five until the sunset and the battle was suspended for the day, and the warriors of both sides, weary and wounded, retired to their tents for rest and for having their injuries attended to. After this, for an hour, soft music was played, soothing the warriors to their rest. That hour was spent, says the poet, without a word about war or hatred and was an hour of heavenly bliss, and it was a glad sight to see. One can see herein what the great lesson of the Mahabharata is.
