As a perfume doth remain
In the folds where it hath lain,
So the thought of you, remaining
Deeply folded in my brain,
Will not leave me; all things leave me -
You remain.

Other thoughts may come and go,
Other moments I may know
That shall waft me, in their going,
As a breath blown to and fro,
Fragrant memories; fragrant memories
Come and go.

Only thoughts of you remain
In my heart where they have lain,
Perfumed thoughts of you, remaining,
A hid sweetness, in my brain.
Others leave me; all things leave me -
You remain.
