My LifeMasaoka Shiki lived from 1867 to 1902, so fairly recent in the world of haiku. It is impressive that his haiku is regarded as meaningful as those of Basho and other historic greats.
Sadly, Shiki had a rough life, including struggling with tuberculosis. He died when he was only 35.
That might give some insight into his famous poem:
My life -
How much more of it remains?
The night is brief.
Shiki, more than most of us, might have had reason to ponder this sort of issue.
Here is a bookmark I made of this haiku. I took the photo of a a candle I'd made a long time ago, which is now nearly at its end.
