You still do not know how deeply these charming ways of yours have settled into my heart, such that only my soul truly knows it.

There is a tender, affectionate complaint in this couplet, where the lover marvels at how oblivious the beloved is to their own mesmerizing charm. Every subtle gesture and grace of the beloved has quietly seeped so deep into the lover's heart that words cannot measure its impact. By saying 'only my soul knows', the poet captures an intimate devotion so profound that only the innermost self can bear witness to it.
