quiver

My lips still quiver when I think about her smile.

love one another, but make not a bond of love: let it rather be a moving sea between the shores of your souls. fill each other's cup but drink not from one cup. give one another of your bread but eat not from the same loaf sing and dance together and be joyous, but let each one of you be alone, even as the strings of a lute are alone though they quiver with the same music.
