Now in the cellar there were two tubs of water, one on the right hand and the other on the left. Golden Tress led Ivan forward and said to him, "Drink from the tub on your right hand." Ivan drank and drank deeply while his beautiful mother watched him closely, and when he was finished she asked, "Well, what strength is in thee?" "I am so strong," said the youth, "that I could turn over the whole castle with one hand." "Drink again," said Golden Tress, very quietly. Ivan drank again and drank deeply. "What strength is in thee now?" asked his mother. "I am so strong," said he, "that, if I wished, I could turn the whole world over." "That is very great strength," said Golden Tress. "Now move these tubs of water so as to make them change positions. Place the right-hand tub on the left and the left-hand tub on the right." Ivan did so with perfect ease. "Now," said Golden Tress, "let me tell you why I asked you to do this. In one of these tubs is water of strength, but in the other, water of weakness. Whirlwind always drinks the water of strength, and puts it on the right side, so we must mislead him or you will never be able to overcome him." Thereupon they made their way up the winding stairway to the apartment of Golden Tress, in which stood the shining throne made from a single emerald. Golden Tress sat down upon this throne and composed herself, as if she were expecting a visitor. "In a short time," she said, "Whirlwind will fly home. Come and hide beneath my purple robe so that he may not be able to see you, and when he enters and runs to try to embrace me reach out your hand, which is now a hand of heroic strength, and seize his club. He will rise high and ever higher, but do not therefore release your hold upon his club. He will fly out of the window in the roof, and will carry you over seas and over precipices, but do not in dizziness release your hold upon his club. After a while Whirlwind will grow weak and will return to this palace and go down to the cellar, but do not release your hold upon his club. He will drink of the water in the tub on the right hand, but see that you drink meanwhile of the water in the other tub. "When he has drunk well, he will grow weak, and then you must take his sharp sword from his girdle and hew off his head with it. As soon as his head falls to the ground you will hear voices behind you crying, 'Strike again, strike again.' But these will be the voices of tempters, and your answer to them must be, 'A hero's hand strikes once to kill, but never once to maim.'"
