Maria Montessori,
The Montessori Method
“ The child is blindfolded, or the teacher may stand behind him, speaking his name, in a whisper and from varying distances. I establish a solemn silence in the schoolroom, darken the windows, have the children bow their heads upon their hands which they hold in front of their eyes. Then I call the children by name, one by one, in a whisper, lighter for those who are nearer me, and more clearly for those farther away. Each child awaits, in the darkness, the faint voice which calls him, listening intently, ready to run with keenest joy toward the mysterious and much, desired call. ”
