kharas ca karkasaih ksattah

Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
O Vidura, the asses ran hither and thither in herds, striking the earth with their hard hooves and wildly braying.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Asses also feel very respectable as a race, and when they run in flocks hither and thither in so-called jollity, it is understood to be a bad sign for human society.
