“Maharaja Yudhishthira was the ideal and celebrated pious King of the world, and still he was greatly afraid after the execution of the Battle of Kurukshetra because of the mass killing in the fight, all of which was done only to install him on the throne. He therefore took all the responsibility for sins committed in the warfare, and to get rid of all these sins, he wanted to perform three sacrifices in which horses are offered at the altar.” (Shrila Prabhupada, Shrimad Bhagavatam, 1.12.34 Purport)
