classic waka stream

let my span of years
be added to your eight thousand—
if it may be so
then keep what thus remains
as a memory of me

Meaning
If my years could be added to your long life, then keep what remains as a memory of me.
Commentary
Book Seven Felicitations

The poem expresses a wish that, having shared time with one blessed with long life, the speaker might at least be remembered. It does not literally mean giving one’s lifespan to another, but rather asks that the speaker be kept in memory alongside the other’s enduring years.
