"It is only after the Second Threshold that the awe-struck Faithful begin to
progressively discover this world through the medium of their higher centres.
About the working of these centres we have already quoted the following words
of St Isaac the Syrian: 'The soul, like the body,has two eyes: but while the eyes of the
body both see things in the same way, those of the soul see them differently; one
contemplates the Truth in symbols and images; the other contemplates it face to face.'
