Mono no aware (物の哀れ) - Literally "the pathos of things", and also translated as "an empathy toward things", or "a sensitivity to ephemera", is a Japanese term for the awareness of impermanence (無常 mujō), or transience of things, and both a transient gentle sadness (or wistfulness) at their passing as well as a longer, deeper gentle sadness about this state being the reality of life.

Metaphors for life on earth

What is a man’s life but a fleeting dream, a passing shadow, a vaporous cloud, a gust of wind, and a swirl of dust?- Rosh Ha Shannah Liturgy

(12) Who can possibly know what is best for a man to do in life—the few days of his fleeting life? they are made like a shadow For who can tell him what the future holds for him under the sun?

(י) יְמֵֽי־שְׁנוֹתֵ֨ינוּ בָהֶ֥ם שִׁבְעִ֪ים שָׁנָ֡ה וְאִ֤ם בִּגְבוּרֹ֨ת ׀ שְׁמ֘וֹנִ֤ים שָׁנָ֗ה וְ֭רָהְבָּם עָמָ֣ל וָאָ֑וֶן כִּי־גָ֥ז חִ֝֗ישׁ וַנָּעֻֽפָה׃ (יא) מִֽי־י֭וֹדֵעַ עֹ֣ז אַפֶּ֑ךָ וּ֝כְיִרְאָתְךָ֗ עֶבְרָתֶֽךָ׃ (יב) לִמְנ֣וֹת יָ֭מֵינוּ כֵּ֣ן הוֹדַ֑ע וְ֝נָבִ֗א לְבַ֣ב חָכְמָֽה׃

Psalms 90:10-12

(10) The span of our life is seventy years, or, given the strength, eighty years; but the best of them are trouble and sorrow. They pass by speedily, and we are in darkness. (11) Who can know Your furious anger? Your wrath matches the fear of You. (12) Teach us to count our days rightly, that we may obtain a wise heart.

Indeed, man is but grass: (8) Grass withers, flowers fade— But the word of our God is always fulfilled!”
