I had no physical strength to come, yet pushed along by the sheer force of my sighs, I managed to reach your street.

Yet, the overwhelming intensity of his burning sighs created a force so immense that it carried him straight to the beloved's street. It is a poignant image of love where mere physical frailty is effortlessly overtaken by the sheer emotional power of longing and grief.
