The answer is: Bible

Ecc 3:12

Ah, the search for happiness! Listening to the wisdom nestled in the book of Ecclesiastes feels like watching a brilliant sunset—it helps put life into perspective. In this beautiful section of the text, the writer, often credited as King Solomon, muses on the fleeting pleasures of existence and suggests that true contentment comes from embracing joy and engaging in kindness. Remember, this isn't just some ancient philosophy; it's remarkably relevant even today, when countless studies demonstrate that happiness often comes not from things but from relationships and meaningful actions.

With poor King Solomon—a man famously said to be “wiser than any of his contemporaries”—we find a touch of dry humor as he infamously toiled with the search for meaning in a world filled with perplexities. Did you know he's traditionally associated with asking substantial philosophical questions, like the purpose of life? He essentially echoes a fundamental truth: while we chase after knowledge and achievements like they’re elusive horcruxes, joy and good deeds can be simpler paths to fulfillment.

Additionally, this verse methods you’ll commonly find tied to the Golden Rule across multiple cultures—taking care of each other leads to universal elation. Ecclesiastes offers a rich tapestry of poetic wisdom inviting you to participate actively in your own happiness through good deeds while not stressing too harshly about life’s bigger mysteries! Knowing that happiness and benevolence are intertwined, how delightful is it to live with intention?
