He wants to leave his beloved because he knows very well that death will certainly part them away. The poet assures his beloved that he will come back, like the sun comes every day The poet promises her beloved, that his returning will be faster than that sun.
Finally asserts that those who truly love each other are neither be parted nor departed.
Ultimately meet in heaven after their physical death.
