classic waka stream

If, like the blossoms,
the world were ever constant,
as they return each year,
then even what has passed away
might come again once more.

Meaning
If this world were as constant as the blossoms that return each year, then even the past that has gone might come back once again.
Commentary
Book II, Spring Poems (Part Two)

Though blossoms seem fleeting as they fall, they bloom again each year in the same way. Reflecting on this, the poet suggests that what appears enduring in human life is in fact more transient, and that human existence itself may be the more fleeting and impermanent.
