Life can present many transitions, especially in such fast-moving days as these. And collective mortal history is itself a piling up of layers on layers of transitions. The human, temporal mind would split up continuous, timeless being, would slice it up into episodes, phases, stages, eras: a great skein of beginnings and endings. And they can bring along with them discomforts and uncertainties.
Transitioning from youth to maturity; switching from an old job to a new one or from busy employment into relaxed retirement; shifting from one set of economic conditions to another; moving from the single state into marriage, from one city or country to another, from high school to college, and so on—these are familiar kinds of events. Adapting to change is not always simple and smooth. In fact, Mary Baker Eddy points out in Science and Health: "An unsettled, transitional stage is never desirable on its own account." Science and Health, p. 65 Even though human changes in scenes and conditions can't be altogether avoided, we can deal with the unsettledness of big and small shifts in ways that are scientific and spiritual.
Change doesn't have to be disturbing
or unsettling; that's not a rigid law.
