Wouldn't "doors" (Türen) be more appropriate?
No suggestions here :(
with "doors" i agree.
underneath your hush- survival (if you read it as "überleben") or about life or beyond life or above life*grin (these lyrics are really good to reflect on the meaning of words^^)
behind your end on a word....or after your end- unto a word....mhm^^
i love this song, 'cause it's so different...just from a different life ^^
