O cruel one, I am losing my senses with the morning light; a lover's guest is passing by for a moment.

This profound couplet captures the delicate agony of the lover. The poet is addressing the 'Zalim' (the cruel beloved or fate), asking if he should abandon his sense of self. The reason? Because the beauty of the dawn-lit evening is making him feel so transient, so like a mere, temporary guest. It's a beautiful portrayal of emotional intoxication and the fleeting nature of sublime moments.
