"We discovered that education is not something which the teacher does, but that it is a natural process which develops spontaneously in the human being"

Maria Montessori is stating that education is not something that is exclusively taught by a teacher. Instead, education is a natural procedure that occurs within all humans and develops on its own. This suggests that education is not just about getting info from an instructor, however rather it is about the person's own innate desire to find out and grow.
