":The Coptic monks of the desert knew only a single word and a
single struggle for designating both the mind and the heart.
We tend to separate the mind from the heart.  We like to fill
the mind; yet, we forget the heart.  Or else, we fill the heart
with information that should fill the mind.  Nevertheless, the
two work differently; the mind learns; the heart knows.  The
mind is educated; the heart believes.  The mind is intellectual,
speculative; it reads and speaks.  The heart is intuitive,
mystical; it grows in silence.  The two should be together; and
they should be brought together in the presence of love."
