* "Pour your spirits" refers to Lady Macbeth urging Macbeth to confide in her, to tell her his thoughts and fears. She wants him to open up completely and share his deepest feelings with her.
* "Thine ear" is simply a poetic way of saying "your ear" - meaning she's ready to listen without judgment.
The overall meaning:
Lady Macbeth is trying to encourage Macbeth to trust her and rely on her for support. She wants him to see her as a confidante, someone he can turn to in his time of need.
This is ironic, however, as Lady Macbeth is herself manipulative and ambitious. She uses this language to gain Macbeth's trust and manipulate him into committing regicide.
Here's what it implies about Lady Macbeth:
* Desire for control: She wants to be involved in all aspects of Macbeth's plans and decisions.
* Ambition: She wants to share in Macbeth's ambition and climb to the top of power with him.
* Deception: She hides her true intentions behind a facade of support and compassion.
In essence, Lady Macbeth uses this phrase to establish herself as Macbeth's confidante, paving the way for her manipulation and influence over his actions.
