I hold this to be the highest task of a bond between two people: that each should stand guard over the solitude of the other. For, if it lies in the nature of indifference and of the crowd to recognize no solitude, then love and friendship are there for the purpose of continually providing the opportunity for solitude. And only those are the true sharings which rhythmically interrupt periods of deep isolation.

Rainer Maria Rilke (with thanks to Maria Popova)

Solitude, that contemplative necessity, can be a difficult thing. Perhaps it requires the solitary to relinquish all relationships and move out into the desert, either literally or metaphorically, as so many have done over the years. Or else it may be a thing of closed doors, of jealously guarded time in a study, or a bathroom, metered out in hours or minutes and maybe feared or resented as infidelity.

But it seems as if another way is at least possible, as Rilke explains: a delicate and sometimes perilous adventure in shared risk and trust, whose rewards can be as great, perhaps, as those of the relationship itself. I once used the phrase “married eremitism” here, and clunky though it is it does seem to sum up this companionable solitude, and how, eventually, it can become somehow a comfortable thing, sturdy and quiet but eager, almost, in its own way. It may be one of the loveliest gifts two people can give to each other.
