The earth is at the same time
mother,
She is mother of all that is natural,
mother of all that is human,
She is the mother of all,
for contained in her
are the seeds of all.
The earth of humankind contains all moistness,
all verdancy,
all germinating power.
It is in so many ways
fruitful.
All creation comes from it.
Yet it forms not only the basic
raw material for humankind,
but also the substance
of the incarnation
of God’s son.
–Hildegard of Bingen
I always rather liked her style of mysticism. :)
