The character reflects on the paradox of happiness and its relationship with mortality. While happiness is a desirable state, it becomes burdensome when it starkly highlights the inevitability of death. This realization leads to questioning the value of joy if it simply serves to emphasize our ultimate fate.
The sentiment suggests that moments of happiness may be fleeting and can evoke a deeper awareness of life's fragility. Instead of being purely uplifting, happiness can force us to confront uncomfortable truths about our existence, creating a conflict between the desire for joy and the acceptance of our mortality.
