Transience and impermanence are hallmarks of life, from the changing elements of the seasons to the changing seasons of our own lives. Nothing lasts forever; it all fades away. This is the pathos of life, the mono no aware.
Mono-no aware: the ephemeral nature of beauty – the quietly elated, bittersweet feeling of having been witness to the dazzling circus of life – knowing that none of it can last. It’s basically about being both saddened and appreciative of transience – and also about the relationship between life and death. In Japan, there are four very distinct seasons, and you really become aware of life and mortality and transience. You become aware of how significant those moments are.

The most celebrated example of a natural phenomenon rich in mono no aware is the spectacle of cherry blossoms.
