I think, therefore iambic pentameter

The tremble-feathered little bird

Beating fierce against your ribcage,

Cannot hear a calming word
Through the flutter of her rage.

She needs to learn to listen, so you must
First begin by showing her the way.
You must be the first to trust.
Attend to what your fledgling heart may say.

Learn what she knows. Then once you know,
And she feels that you understand her fear,
You will have earned the right to show
the rest of what's true, and she'll finally hear.

The heart needs the mind, and the mind needs the heart.
Whichever one can listen, ought to start.
