How my memory treasures every sweet stray moment of our past — handclasp, kiss and heart-beat, the passion of those dear unfathomable eyes, the rustle of garments, the gliding steps and lingering farewells!

The speaker dwells on the sensory minutiae of remembered intimacy—touch (“handclasp”), breath and pulse (“heart-beat”), sight (“dear unfathomable eyes”), and even sound and motion (“rustle of garments,” “gliding steps”). The piling up of concrete details suggests that love persists less as an abstract idea than as a hoard of vivid impressions, preserved and replayed by memory. The phrase “sweet stray moment” implies these were fleeting, perhaps stolen or irrecoverable encounters, and the “lingering farewells” hint at separation or loss. Overall, the line dramatizes how recollection can intensify desire: memory becomes a treasury that both comforts and reopens longing.
