Poem by the Finnish writer Johann Ludvig Runeberg (1804–77) who wrote in the Swedish language

Joy and sorrow

Joy and sorrow both

resided in my heart,

joy in the one chamber,

sorrow in the other.

irreconcilably separate,

first the one ruled

then the other, solely.

Since the one and only came here,

she’s opened, it would seem, the door

and has united both,

for my joy is sadness

and my sorrow bliss.
