I discovered Martin Buber while taking an undergraduate philosophy class when I read I and Thou. Many is time I have wishe I knew German so I could read his works in the original. Here is a lovely passage that adds to my collection of quotations about valuing the ordinary:
One should hallow all that one does in one's natural life. One eats in holiness, tastes the taste of food in holiness, and the table becomes an altar. One works in holiness, and raises up the sparks which hide themselves in all tools. One walks in holiness across the fields, and the soft songs of all herbs, which they voice to God, enter into the song of our soul.
-- Martin Buber
