And the Lord said in His heart: “I will not again curse the ground any more for man’s sake”
Noah knew God’s thought. After the flood Noah found a tremendous sense of awe within him. It was no longer right [to Noah] that a person should expand himself only according to his own will. Rather, one needs to reign in his spirit.
From this [new understanding of what is required of an individual, to practice restraint], Noah understood that it was the will of God to never again curse the Earth.
How does Noah know what God is thinking? Because Noah is feeling it, and that must mean God is feeling it.
Noah is overcome with a sense of awe. He comes face-to-face with how small he truly is, accepts his nothingness, and in doing so actually opens himself up to receiving so much more. When he is no longer conscious only of himself, but the greatness beyond him, now he can trust that his thoughts and feelings are pure. And as was seen in Bereishit, the Ishbitzer believes one’s thoughts and emotions are actually God’s.
So is the Ishbitzer saying you’re a prophet right now, and everything you’re thinking is divine and straight from the mind of God? Yes and no. It is explicit that you have to reign yourself in. You can’t live by doing whatever you want. That just makes you an asshole. It is this beautiful (terrifying?) space in-between that you are trying to reach, where you are not doing ANYTHING for yourself. Rather, you are attuned to what is right and true, and you live your life according to that, even in the absence of “explicit” approval from God/Torah/Law.
And perhaps it is in this hope, this faith that humanity can achieve a state of being where all they “freely” do and think is in fact divine, that Noah understands God will never need to curse the Earth again.
