"But, Auntie, didn’t he say: ’What I say unto you I say unto all.’ If we love him we shall keep all his commandments. That is why I am sorry Uncle Raymond has taken away my _Science and Health_. I want to understand it like Cousin Alicia does; then some day, if I know little boys or girls ill like I was, I could heal them. It makes me so sorry now that I cannot study. I have written to Cousin Alicia to help me. I know she will. It has been so difficult all day to stand ’porter at the door of thought.’ Such a lot of unkind thoughts would keep trying to get in. I know I must not let any of them in, and Cousin Alicia will help me to keep them out." "I am afraid I do not quite understand, Carol." "Don’t you, Auntie? I have a little book that will explain. It is called ’At the Door.’ Our mind is like a beautiful white mansion, and thoughts are like people who go in and out. If we let unkind thoughts pass in, all kind thoughts go away. Self-pity isn’t at all a nice person, I have had such difficulty to keep him out all day, especially when I remembered that Father knew I was studying _Science and Health_, and he did not take it away from me." "I will tell that to Uncle Raymond, dear, perhaps it will cause him to alter his decision." "Thank you, Auntie; I know it will be all right. I have only to be patient. They have all gone away now, self-pity and indignation, and anger. If I keep my mansion so full of love, there will be no room for them to squeeze in, will there?" "No, darling. Now go to sleep. I will take the little book down with me and read it." Mrs. Mandeville remembered as she went downstairs her visit three years ago to Carol’s home. Then she would have described him as a very spoilt child, making allowance for his illness, he was fretful, selfish, exacting. What had wrought such a marvellous change? The physical healing seemed slight in comparison. CHAPTER IV.--A WELCOME LETTER. Carol had been at the Manor a week before he received the eagerly expected letter from Cousin Alicia. Mrs. Mandeville brought it herself to the school-room for him. "What a lucky little boy to get such a fat letter! I wonder the post-office didn’t decline to bring it for a penny," she said smiling at his radiantly happy face. Then turning to Miss Markham, as lessons were about to commence, she asked: "May he be excused for a little time, Miss Markham? I know he will like to take it to his room and read it quietly there." "Oh, thank you, Auntie; thank you, Miss Markham," as the asked-for permission was quickly accorded, and he ran off with the treasured letter. Half an hour later he sought Mrs. Mandeville in her morning-room. "Auntie, would you like to read my letter?" "Indeed, dear, I should, if you would care for me to." "Yes, Auntie. I would like you to read it very much. I knew Cousin Alicia would help me to understand. It has been just like having a talk with her. She always makes me feel happy."
