The heart, a muscular organ essential to blood circulation, has long symbolized emotion and spirituality in literature. Authors like Alexandre Dumas highlight its endurance, likening joy to "dew on the ground after a long drought," while ʻAbdu'l-Bahá portrays it as a vessel for divine affection, encouraging readers to "form some idea of the extent of Thy love.
" The Earl of Chesterfield underscores its function as the gateway to human connection, advising the use of "eyes and ears" to reach the "heart." These diverse viewpoints illustrate the heart as both a biological necessity and a symbol of human experience, linking the physical and the metaphysical.
