Poem: a tanka by Saigyo Hoshi

Here is an untitled poem, a tanka, by Japanese poet Saigyo Hoshi (1118-1190).

Now indeed I know
that when we said "remember,"
and we swore it so,
it was in "we will forget"
that our thoughts most truly met.

(The original source of this poem and the original source of its anonymous translation into English are both unknown. The poem above was quoted in Benet's Reader's Encyclopedia.)
