We live solely on the longing for you. If this desire does not exist, then there is no life at all.

This couplet captures the sheer intensity of love where longing itself becomes the breath of life. The poet confesses that their existence isn't sustained by actually possessing the beloved, but merely by keeping the tender desire for them alive in the heart. If that yearning were to disappear, life might go on mechanically, but its true soul and purpose would be completely lost.
