Below is some of what she says; I think you will also find real similarities to what I have said about solitude throughout the years here, along with what the Cistercians, the Camaldolese, the Franciscans, and even what the Carthusians say regarding the relationship of solitude and community. In all of these spiritualities there is a tension between solitude and community and each group works out this tension (or, maybe better said, negotiates and lives this tension creatively) in somewhat different ways. The tension is never simply ignored or obviated; it is lived faithfully, and the result is either a healthy and authentic coenobitism or a healthy and authentic eremitism. Again, St. Teresa, for example, wanted nuns who would also be hermits and therefore, she created a coenobitical "eremitism" which at once cut Carmel off from the world around them with a strict enclosure -- stricter than occurred with the origin of the Order, perhaps; but at the same time, the desert she created was meant to allow for an exposure to reality (to God and one's deep self as well as to one's Sisters); it was a "solitude in which a woman's life could develop and expand"! Ruth Burrows, OCD, writes:
[[To be alone with Him Alone is, at bottom, to be detached from self, with mind and heart directed to pleasing God only --- something that is impossible without generous effort, searching purification, and --- let us not overlook it --- personal maturity. It is possible for someone to live in physical solitude, to follow a strict Rule of life, pray, experience great devotion or desolation, yet remain basically egotistical, undeveloped, and emotionally stunted: alone, not with God, but with the self and its projections of God. John of the Cross insists that we simply cannot, of ourselves, divest ourselves of our egotism. God has to act both directly and indirectly. Other people are his chosen instruments, and we have an absolute need of them in order to mature emotionally, intellectually, and spiritually and to learn how to love --- our life's greatest task.]] Later Burrows writes:
[[All human maturation and growth towards union with God demands a creative tension between solitude and community. Understood in a truly spiritual/Christian sense, we cannot have the one without the other, and each thrives in mutual proportion. Each of us must stand absolutely alone before God, assuming full responsibility for our attitudes and choices. At the same time, none of us can come to self-knowledge and maturity without others. The more truly solitary and personal the individual member, the more authentic the community --- a genuine communion of mind and heart. . .. Understanding the meaning of solitude and being faithful to it, and at the same time forgetting self in the service of community, enables divine Love to bring to being our true personhood. When that is so then, most truly, we are alone with God alone.]]
Regarding your question on percentages, I never measure anything regarding solitude and community in that way. It is not helpful at this point. Instead, I recognize I am called to live with and for God alone and I do what is necessary to ensure that. That will mean meeting with my Director regularly, joining with my faith community at the parish when I can, doing the personal work I have committed to as part of my ongoing personal formation, and being accessible if someone needs to meet with me, including spiritual direction clients. But it will also mean living most, if not all of every day, with God for the sake of God and others --- alone in my hermitage. So long as prayer continues to support these activities and these activities continue to call me back to prayer in solitude, and so long as I continue to experience God calling me to all of this and find myself growing as a person in Christ, I think I am living exactly the kind of solitude God calls me to. And, though I am not a cenobite, I think it is the same kind of solitude St. Teresa wanted for her Sisters, specifically, "a solitude in which a woman's life could develop and expand," and do so in and with God.
