A person who has extraordinary bodily strength is called baliyan. When Krsna killed Aristasura, some of the gopis said, "My dear friends, just see how Krsna has killed Aristasura! Although be was stronger than a mountain, Krsna plucked him up just like a piece of cotton and threw him away without any difficulty!" There is another passage wherein it is said: "O my dear devotees of Lord Krsna, may the left hand of Lord Krsna, which has lifted Govardhana Hill like a ball, save you from all dangers."
