The speaker declares that she thinks about "thee," addressing a lover. Her lover is like a tree, and her thoughts are like vines wrapping around its trunk so that you can hardly see the tree itself. However, she tells the lover, she doesn't want to cover or strangle them. After all, the lover is better than the speaker's thoughts about them. Instead, she tells the lover to reassert themselves by shaking off the vines of the speaker's thoughts so that they shatter on the ground. After all, when the speaker actually has the privilege to be near her lover, she doesn't spend time thinking about them. Instead, she is simply and happily near them.
