Why Existence Is Not Pure Delight?
The answer is that life is regulation, and regulation only exists when deviation is possible. If there were no possibility of disorder, there would be nothing to regulate. If there were no entropy, there would be no metabolism. If there were no prediction errors, there would be no learning. If there were no threats, there would be no survival.
So suffering is not added onto life afterward. It emerges from the fact that life is an active process of combination of how to stay in homeostasis. Ironically, pleasure itself only makes sense because regulation exists. Relief from thirst is pleasurable because thirst exists. Warmth is pleasurable because cold exists. Safety is pleasurable because danger exists. Rest is pleasurable because fatigue exists. Pleasure is the subjective experience of successful regulation. Suffering is the subjective experience of unsuccessful or threatened regulation.
Why doesn't happiness last?

Pleasure is one of the informational signals that help the resistance continue.

That is why philosophy of permanent happiness has ever been scientifically convincing. Firstly, the feeling of happiness is not a goal but information for the process of life, secondly, constant happiness would mean the end of information and the end of life A permanently satisfied organism would stop updating, exploring, repairing, and protecting itself and ... The goal of life is not happiness nor sufering but homeostasis within continuation and unfolding of the living process. Pleasure and suffering are complementary informational signals that regulate that unfolding.
This is why the idea of Process Mindfulness © feels so different from mainstream mindfulness. It not trying to maximize pleasant moments. Instead, it's trying to understand the dynamics of the process itself. That is a genuinely systems-theoretic way of thinking about human existence.
