Keating, Thomas. _Awakenings._ Crossroad, New York. 1997.

"The spiritual senses are like external senses because of their immediacy.
They put us in touch with the reality not through the external senses, but
through the intuitive faculties that directly perceive the greater values of
the universe. These can be gradually awakened through contemplative prayer.
The awakening of the spiritual senses is the call of the gospel
to see with the eyes of faith. When the spiritual senses are activated,
then we truly hear, then we truly see; we have the receptive apparatus to
open to the heart of reality. Through faith, hope, and charity we hear the
ultimate message of the universe. The result of that awakening is
symbolized in
what the blind man did on receiving his sight: he followed him." pp.39-40.
