With the stains of the crimson-dyed forehead, at night, we also spread the blossoms upon the bed.

This beautiful couplet paints a picture of deep, shared intimacy. The poet says that at night, they used to sleep on a bed adorned with flowers, comparing the bedspread to the stains left by a red rose. The stains (daag) here symbolize the mark of love, a beautiful, permanent memory. It suggests that the speaker's life, and their rest, were marked by the intensity and beauty of the beloved's love.
