The first line is "After I cut off the arms that reached out to me"
"And after I boarded up all the windows and the doors"

It was probably written in Spanish and translated to English

I believe the Poem you are searching for is "After" by Octavio Paz.

"After chopping off all the arms that reached out to me;
after boarding up all the windows and doors;
after filling all the pits with poisoned water;
after building my house on the rock of no,
inaccessible to flattery and fear;"
