Let mystery have its place in you; do not be always turning up your whole soil with the plowshare of self-examination, but leave a little fallow corner in your heart ready for any seed the winds may bring, and reserve a nook of shadow for the passing bird; keep a place in your heart for the unexpected guests, an altar for the unknown God. Then if a bird sing among your branches, do not be too eager to tame it. If you are conscious of something new - thought or feeling, wakening in the depths of your being - do not be in a hurry to let in light upon it, to look at it; let the springing germ have the protection of being forgotten, hedge it round with quiet, and do not break in upon its darkness. ― Henri-Frédéric Amiel
I think of this in terms of the unexpected in my lab. The unexpected in data (too much of that lately). The chance encounter. You never know.
