this transient world; this fleeting life
A literary, Buddhist-influenced expression emphasizing the impermanence of worldly existence. Often used in reflective or poetic contexts.
仮の世の住まいと思えば、執着も薄れる。
If you think of it as a dwelling in this transient world, attachment fades.
彼は仮の世の無常を歌に詠んだ。
He composed a poem about the impermanence of this fleeting world.
From 仮 (かり, 'temporary, provisional') + の (possessive particle) + 世 (よ, 'world, age'). The phrase reflects the Buddhist view that the phenomenal world is impermanent and illusory.
