Literary authors have long used the term to denote an elusive state of bliss or joyous fulfillment, one that can be as much a lofty ideal as a tangible experience of happiness. At times, writers present felicity as a delicate counterpoint to the pain of lost passion or as the very reward of moral virtue—a state so intense that it transforms ordinary moments into rare treasures [1], [2]. In works that traverse political treatises and theological discourses, felicity transcends mere earthly pleasure to become an emblem of divine favor or the ultimate goal of societal well-being [3], [4], [5]. Meanwhile, in narratives focused on personal relationships, its appearance, whether fleeting or profound, underscores the tensions between human desire and the often transient nature of true contentment [6], [7], [8].
