From early childhood many of us fall unthinkingly into ineffective ways of withdrawing from problems and pressures—even from the sometimes humdrum nature of our lives. Whether our experience would seem to include too much or too little stimulation, it's as if we inherently realize that mortal existence is just not satisfying, and attempt to escape in some fashion.
While the common, materialistic sense of life may seem to go along smoothly enough at times, it can never be counted on over the long haul. Human existence, without spiritual understanding to regenerate it, includes no guarantees of any sort. As Mrs. Eddy asks in Science and Health, "Who hath found finite life or love sufficient to meet the demands of human want and woe,—to still the desires, to satisfy the aspirations?" Science and Health, p. 257.
Don't we all want to find a refuge from mortality's vain promises of fulfillment? We must be careful, though, to find a real haven in which to abide, not just fall unwittingly into yet another version of those same vain promises.
