classic waka stream

In color and scent,
just as in the days of old,
bloom the cherry flowers;
yet the one who lives through years
has changed and grown anew.

Meaning
The cherry blossoms bloom in color and scent just as in the days of old, yet the person who lives through the years has changed.
Commentary
Spring Songs, Book One

A poem composed in lament at having grown old beneath the beautiful cherry blossoms.

The cherry blossoms remain as they were in the past, yet the one who beholds them loses color and scent and comes to old age.

It likely draws on the line from Chinese poetry: “Year after year the flowers are the same; year after year the people are not.”
