"Once a demon named Aristasura entered the village like a great bull with a gigantic body and horns, digging up the earth with his hooves. When the demon entered Vrndavana, it appeared that the whole land trembled, as if there were an earthquake. He roared fiercely, and after digging up the earth on the riverside, he entered the village proper. The fearful roaring of the bull was so piercing that some of the pregnant cows and women had miscarriages. Its body was so big, stout and strong that a cloud hovered over its body just as clouds hover over mountains. Aristasura entered Vrndavana with such a fearful appearance that just on seeing this great demon, all the men and women were afflicted with great fear, and the cows and other animals fled the village.

The situation became very terrible, and all the inhabitants of Vrndavana began to cry, "Krsna! Krsna, please save us!" Krsna also saw that the cows were running away, and He immediately replied, "Don't be afraid. Don't be afraid." He then appeared before Aristasura and said, "You are the lowest of living entities! Why are you frightening the inhabitants of Gokula? What will you gain by this action? If you have come to challenge My authority, then I am prepared to fight you." In this way, Krsna challenged the demon, and the demon became very angry by the words of Krsna. Krsna stood before the bull, resting His hand on the shoulder of a friend. The bull began to proceeded towards Krsna in anger. Digging the earth with his hooves, Aristasura lifted his tail, and it appeared that clouds were hovering about the tail. His eyes were reddish and moving in anger. Pointing his horns at Krsna, he began to charge Him, just like the thunderbolt of Indra. But Krsna immediately caught his horns and tossed him away, just as a gigantic elephant repels a small inimical elephant. Although the demon appeared to be very tired and although he was perspiring, he took courage and got up. Again he charged Krsna with great force and anger. While rushing towards Krsna, he breathed very heavily. Krsna again caught his horns and immediately threw him on the ground, breaking his horns. Krsna then began to kick his body, just as one squeezes a wet cloth on the ground. Being thus kicked by Krsna, Aristasura rolled over and began to move his legs violently. Bleeding and passing stool and urine, his eyes starting from their sockets, he passed to the kingdom of death.
