Hie thee hither,
That I may pour my spirits in thine ear;
And chastise with the valour of my tongue
All that impedes thee from the golden round,
Which fate and metaphysical aid doth seem
To have thee crown’d withal.

– William Shakespeare

Macbeth, Act 1, Scene 5. In her soliloquy Lady Macbeth bids her husband to hurry home so that she can set in motion her plan to spur him to usurp the crown. She uses the metaphor “pour my spirits in thine ear” to describe how she will whisper words of evil and transfer her spirit into Macbeth, as if to possess him. She will use the courage of her woman’s tongue to rid him of everything that holds him back from the crown. Here we are seeing Lady Macbeth aligned with the Witches as the Fourth Witch. In a nod to the weird sisters she says that Macbeth has already been crowned by “metaphysical aid” and “fate.” Now that she views herself as future queen, she will stop at nothing to achieve her goal.
