You must know that there is nothing higher and stronger and more wholesome and good for life in the future than some good memory, especially a memory of childhood, of home.

Context

“My little doves—let me call you so, for you are very like them, those pretty blue birds, at this minute as I look at your good dear faces. My dear children, perhaps you won't understand what I am saying to you, because I often speak very unintelligibly, but you'll remember it all the same and will agree with my words some time. You must know that there is nothing higher and stronger and more wholesome and good for life in the future than some good memory, especially a memory of childhood, of home. People talk to you a great deal about your education, but some good, sacred memory, preserved from childhood, is perhaps the best education. If a man carries many such memories with him into life, he is safe to the end of his days, and if one has only one good memory left in one's heart, even that may sometime be the means of saving us.” source
