Author Paulo Coelho is best known for his beloved 1988 book "The Alchemist," a story that encapsulates his pursuit of spiritual fulfillment in literature and in life. This line, however, comes from a later novel, "By the River Piedra I Sat Down and Wept." The book follows a pair of lovers, former childhood friends, as they navigate a journey through sacred sites in the French Pyrenees. One of the two has become a spiritual guru and miracle worker, and must choose between his calling and his affair. Yet, in the end, valuing one lover’s spiritual growth brings happiness to them both, for herein lies the paradox of happiness: When it is shared it does not diminish, but grows.
