The heart of the soul

The eye or heart of the soul is called the nous. Illness of the soul through sin – both original sin and personal sin – darkens the nous, preventing illumination and deification. Healing of both the soul and the nous results in union with God, the vision of God, deification and theoria (Met. Hierotheos, The illness and cure of the soul; St Andrews Productions, Seeing with the eyes of the soul).
