Context

“or it may come through new intellectual insights, or through experiences which we shall later have to designate as “mystical.” However it come, it brings a characteristic sort of relief; and never such extreme relief as when it is cast into the religious mould. Happiness! happiness! religion is only one of the ways in which men gain that gift. Easily, permanently, and successfully, it often transforms the most intolerable misery into the profoundest and most enduring happiness. But to find religion is only one out of many ways of reaching unity;” source
