A quote from the Hagakure, from the second chapter.

The full quote is:

"In the Kamigata area they have a sort of tiered lunch box they use for a single day when flower viewing.
Upon returning, they throw them away, trampling them underfoot. As might be expected, this is one of my recollections of the capital (Kyoto).
The end is important in all things."

This is, of course, a metaphor for the death of a samurai.
