Here is one way of looking at the question of mistakes from different filters...
Ground and Big Mind
Ground is inherently free from any notions of mistakes or no mistakes. It allows any forms to come and go as Ground itself, as emptiness dancing.
Big Mind, as Ground as emptiness and form, is similarly absent of any notions of mistakes. It is beyond, yet includes, any ideas of mistakes or no mistakes, and anything these ideas point to.
When Big Mind awakens to its own nature, there is the realization that any and all forms are inherently free from mistakes/no mistakes.
Spirit exploring itself
Moving slightly into the relative, yet informed by the absolute, we can say that everything is Spirit exploring and experiencing itself.
I eat icecream, I stub my toe, I sleep, I miss a deadline, I get praise, I forget the name of a Breema sequence when teaching, I decided to stay in the US instead of going back to Norway, I get sick and can't do much for a couple of days, I fail a test of some sort.
All of these, and anything else in any human life and existence as a whole, is Spirit manifesting, exploring and experiencing itself - as emptiness and form, experiencer and experienced, seeing and seen.
And this happens independent of the particulars of the content. No matter what form is doing, it is still Spirit experiencing itself. There is no mistake there. It is inherently free from the possibility of mistake.
The sense or experience of mistakes only come in, and is inevitable, when there is a belief in thoughts. Existence should look this way, so if it conforms, it is no mistake, and if it does not, there must be a mistake somewhere: you made a mistake, I made a mistake, God made a mistake.
