The quote came from a children’s book by Yuko Takao about a little mouse that goes to the concert and is filled the beautiful music there. Afterward, the music lingers and colors her world. Then she writes about it. Now it is there so she can go back and remember the experience. From there, more experiences will add colors and depth to the experience she recorded that night, making the captured moment more meaningful in the past, present, and the future.
I believe that one of the reasons why we write is not only to understand what we are thinking, but also to have a way to add/measure the things that are not measurable, the things that color life, the spirit that breathes life into living. More on that later though.
