The answer is: Bible

Ecc 3:12

Ah, the beauty of simplicity in Ecclesiastes! The rich tapestry of life is woven with threads of joy and benevolence, reminding us that happiness is closely linked to doing good deeds. This isn't just a wise saying—it's practical advice tucked away in the ancient words of the author.

Did you know that Ecclesiastes is often viewed as somewhat mysterious? Many scholars suggest it reflects a voice seeking to understand the chaos of life, balancing pleasure with the inevitability of mortality. Its author, traditionally credited to Solomon, contemplates the futility often found in the pursuit of wealth and status. Instead, he champions a heartfelt, uncomplicated life—a reminder that lasting joy often blossoms in the simplest acts, whether it's a smile, a helping hand, or spending quality moments with loved ones.

Interestingly, the concept of seeking joy through good works isn’t confined to just one holy book! Many cultures and philosophies echo this sentiment. Furthermore, when people do good, hormones like oxytocin and serotonin flood their bodies, creating the very happiness Ecclesiastes talks about—as if articulating wisdom found in both ancient texts and modern science!

So, the next time you find yourself in the depths of pondering life, remember that there’s immense value — not just in individual pursuits of happiness but also in embracing a spirit of generosity towards others. It's a beautiful way to engage with the world around you!
