Your bond cannot be hidden, nor can secret love remain. The entire world has known this, so do not let your mercy diminish.

This couplet beautifully suggests that genuine friendship and deep love are impossible to keep hidden. They eventually become evident to everyone around. The poet expresses that your bond cannot be concealed, and secret affection doesn't remain a secret for long. Since the entire world has already come to know about it, the plea is, "Please do not let this compassion or kindness between us fade away now." It's a heartfelt request to cherish and maintain a relationship that has become openly recognized and known to all.
