Yes

I don't know Who — or what — put the question, 
I don't know when it was put. 
I don't even remember answering. 
But at some moment I did answer Yes 
to Someone — or Something — 
and from that hour I was certain 
that existence is meaningful and that, therefore, 
my life, in self-surrender, had a goal.
