A Gas Butterfly

Tell me what's happening to me?
Why is my heart beating so fervently?
why has this madness, like a wave,
Broken through the rock of habit?

Is it my strength or just my torment
I'm too disturbed to tell:
From the shimmering lines of life
I extract a forgotten phrase...

Is it a thief who turns his lantern
Upon the crowd of dreary letters?
I can't help reading the phrase,
But haven't the strength to go back...

It really had to flare up,
But it only harries the darkness;
All night, like a gas-flame butterfly
It trembles, but cannot escape...
