"Why does happiness disappear so quickly?"
Haru murmured while watching the sunset.
Noa smiled. "Maybe it's beautiful because it's fleeting."
"But I wish it would last longer."
Simon joined. "Epicurus said pleasure is the good. But he sought lasting pleasure."
"Lasting pleasure?"
"Not momentary joy, but peace of mind. Ataraxia—a state of tranquil equanimity."
Noa supplemented. "Exciting happiness quickly becomes familiar. But calm satisfaction lasts longer."
Haru thought. "The types are different."
"In Buddhism, attachment is said to be the cause of suffering," Simon continued. "When you try to grasp happiness, it escapes."
"Why?"
"Because change is inevitable. All is impermanent."
Noa said quietly, "Accepting happiness's transience might be happiness itself."
Haru felt a contradiction. "If you accept it, won't you stop seeking happiness?"
"The way you seek changes," Noa answered. "As experience, not possession."
Simon gave an example. "Picking a flower or admiring it."
"If you pick it, it withers," Haru understood.
"Yes. When you try to fix happiness, it breaks."
Noa showed another perspective. "But transience itself can strengthen happiness."
"What do you mean?"
"Knowing it will end soon makes you treasure the present."
Haru nodded. "Limitation increases value."
"Similar to Heidegger's 'Being-toward-death,'" Simon said.
"Being-toward-death?"
"Death showing finitude creates life's meaning."
Noa nodded deeply. "Nothing special in what continues forever."
Haru stared at the sunset. "This moment will never come again."
"That's why it's beautiful," Simon said quietly.
Noa asked, "But can we preserve happiness in memory?"
"Happiness in memory fades," Haru said.
"That's also part of transience," Simon acknowledged. "Proust depicted memory's imperfection."
"In Search of Lost Time?"
"Yes. Past happiness cannot be recovered. But it takes on new meaning in recollection."
Noa smiled. "Happiness is lived twice. In experience and in memory."
Haru pondered. "So it's fleeting, but doesn't disappear?"
"It remains in transformed form," Simon said. "As a trace."
Noa added, "And that trace becomes the foundation for the next happiness."
Haru asked curiously, "Does happiness accumulate?"
"Not directly, but as sensitivity," Noa explained. "Those who've experienced happiness can find it again."
Simon quoted a philosopher. "Aristotle said happiness is a habit."
"A habit?"
"Eudaimonia. Living well. Not a temporary emotion, but an entire way of life."
Noa empathized. "The accumulation of happy moments creates a happy life."
Haru took a deep breath. "Not mourning that it's fleeting, but accepting it."
"And savoring that transience," Simon said.
Noa quietly added, "Japanese aesthetics, mono no aware."
"Mono no aware?"
"Sensitivity to the transient. Seeing transience as beauty."
Haru reached toward the sunset. "Can't grasp it, but it's certainly there."
"That might be happiness's essence," Simon smiled.
Noa said finally, "Because it's fleeting, we live in the now. That might be the answer."
The three gazed at the sunset. That moment was already becoming the past.
But its beauty was etched in their hearts. Fleeting, yet certain.
