Read- and Weep at the Beauty

Inside this clay jug there are canyons and pine mountains,
         and the maker of canyons and pine mountains!
     All seven oceans are inside, and hundreds of millions of stars.
     The acid that tests gold is there, and the one who judges jewels.
     And the music from the strings no one touches, and the source
         of all water.
     If you want the truth, I will tell you the truth:
     Friend, listen: the God whom I love is inside.

Robert Bly's translation of a poem by the great Indian poet, Kabir.

Which made me think of another quote, this one from Lao Tzu:

We shape clay into a pot, but it is the emptiness inside that holds
whatever we want.
