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 held together; and they should be brought together in the presence of God.
