The heart and mind most often agree on what they don't want and want to avoid and this is then realized.
To subject outer intention to your will, you have to wipe all negative thought from your mind and establish harmony between the heart and mind in your positive efforts.
This is why outer intention can work outside of your will.
It is not about forcing your own script on the world so much as considering it possible, allowing the alternative to be realized and allowing yourself to receive.
