A person's body usually goes quite out of control. If he wishes to hold up one foot, his foot will not obey him; for one moment it will go up, but after that it will not obey any more. If he goes to the photographer who says, "Steady", he begins to move at once. The word "steady" alone makes him shake, because it reminds him of his helplessness. Without the word "steady" he was all right, but his word brought his weakness before him, and weakness of the body expresses weakness of mind.
