The list author says: "Ways of Mystical Union: The individual experiences of the greatest mystics of the Eastern Church more often than not remain unknown to us. Apart from a few rare exceptions the spiritual literature of the Christian East possesses scarcely any autobiographical account dealing with the interior life. The way of mystical union is nearly always a secret between God and the soul concerned, which is never confided to others unless, it may be, to a confessor or to a few disciples. What is published is the fruit of this union: wisdom, understanding of the divine mysteries, expressing itself in moral teaching or in advice for the edification of one's brethren. As to the inward and personal aspect of the mystical experience, it remains hidden from the eyes of all."
