[[Hi Sister, when you write about having the heart of a hermit and moving from isolation to solitude do you mean that someone comes to this through some form of trauma or serious personal wounding and alienation? Is this necessary? Can a person who has never been hurt or broken develop the "heart of a hermit"?]]
In any case, the heart of a hermit is created when a person living a desert experience also learns to open themselves to God and to live in dependence on God in a more or less solitary context. One need not become a hermit to have the heart of a hermit and not all those with such hearts become hermits in a formal, much less a canonical way. In the book Journeys into Emptiness (cf.,illustration above), the Zen Buddhist Master Dogen, Roman Catholic Monk Thomas Merton, and Depth Psychologist Carl Jung all developed such hearts. Only one lived as a hermit --- though both Dogen and Merton were monks.
As I understand and use the term these are the hearts of persons irrevocably marked by the experience and threat of emptiness as well as by the healing (or relative wholeness) achieved in solitary experiences of transcendence and who are now not only loving individuals but are persons who are comfortable and (often immensely) creative in solitude. They are persons who have experienced in a radical way and even can be said to have "become" the question of meaning and found in the Transcendent the only Answer which truly completes and transforms them. In a Farewell to Arms, Hemingway said it this way, [[The World breaks everyone and then some become strong in the broken places.]] The Apostle Paul said it this way (when applied to human beings generally), "My grace is sufficient for you, my power is perfected in weakness."
Hermit hearts are created when, in a radical experience of weakness, need, yearning, and even profound doubt that will mark her for the rest of her life, she is also transfigured by an experience of God's abiding presence. A recognition of the nature of the hermit's heart is what drives my insistence that the Silence of Solitude is the goal and gift (charism) of eremitical life; it is also the basis for the claim that there must be an experience of redemption at the heart of the discernment, profession, and consecration of any canonical hermit. While she in no way denies the importance of others who can and do mediate this same presence in our world, the hermit gives herself to the One who alone can make her whole and holy. She seeks and seeks to witness to the One who has already "found" her in the wilderness and found her in a way that reveals the truth that "God alone is enough" for us.
