“All material in nature,

the mountains and the streams and the air and we,

are made of Light which has been spent,

and this crumpled mass called material casts a shadow,

and the shadow belongs to Light."

- Louis Kahn

"And now here is my secret, a very simple secret; it is only with the heart that one can see rightly, what is essential is invisible to the eye."

- Antoine de Saint-Exupery, The Little Prince
