Purification, illumination and deification

According to Maximus the Confessor, “the sign that we have passed the stage of purification is that we have been released from pain and pleasure, the sign that we have passed, or are going through, the stage of illumination is our deliverance from ignorance and forgetfulness of God; and the sign that we have reached deification is our liberation from fantasy” (In Met. Hierotheos, The illness and cure of the soul, p. 47).
