Who knows what will become of me until morning in this pain of separation, when my heart has slipped out of my control right from the evening.

The poet captures the quiet terror of facing a long night of separation from the beloved. Dusk has only just fallen and the heart is already restless and slipping out of control, making him dread how he will survive until morning. It is a poignant picture of emotional vulnerability, where the anticipation of loneliness is almost as overwhelming as the night itself.
