Purport
The Asura—class of men on the surface of the world want to enjoy life of sense gratifcation even at the cost of other's happiness. Inorder to fulfil this ambition of life the Asuras, specially the kings or the state executive heads, belonging to the unbeliever class of men, try to equip themselves with all kinds of deadly weapons preparing to bring about a war in the peaceful society. They have no other ambition than personal aggrandisemnt and as such the mother earth feels overburdened by such undue increase of military strength. By increase of such Asurik population the principles of religiosity becomes hamperred and the total result is that all the people of the world become unhappy, specially the devotee or Deva class of men feel too much for this anomalies of the Asurik civilization of self aggrandisement.
In such situation only the Personality of Godhead incarnates just to vanquish the unwanted Asuras and to re-establish the ture principles of religiosities. The misssion of the Lord Sri Krishna was this and He fulfilled it.
