I thought of you when I read this quote from “Spiritual Friendship (Cistercian Fathers)” by Aelred of Rievaulx, Marsha L. Dutton, Lawrence C. Braceland –

What plot of land or what stream turns up only one stone of a single kind? Or what forest produces only one tree of a single species? Thus among non-sentient beings, a kind of love of companionship comes to light, since not one of them is left alone, but each is created and conserved in a kind of society of its own class. But among sentient creatures, who could easily express how great a mirror of friendship and how great an image of a loving society they reflect?

Aelred of Rievaulx, Spiritual Friendship, I.54.
