One would be experience, such as either watching others or through direct experience. I would also say that there is a state of being that I have been alluding to where one somehow knows, without there being anything concrete to point ones intellect at. Its a knowing that originates from the feeling area.
It sounds like you're describing "flow-state" which many high-performance athletes report experiencing, funny enough, even rock-climbers.
A "flow-state" is achieved by training your body to move without sending "questions" to your prefrontal cortex.
One rock-climber described a sort of "waking up" when they would reach the top of a climb.
It was as if their body was acting automatically.
This sounds like the exact opposite of "free-will".
It seems like it is, but I don't believe so. Feeling is another state that I believe is probably our natural state. It is much quicker than thought/intellect state, and I believe due to that it is impossible to grasp intellectually what is taking place.
As I mentioned earlier, I'm not certain such a thing as true free will exists. I know that in situations that involve intellect that there can be a limited expression, however it is confined to the realm of syntax. But there is much to the world that is not chained to that room. I will expound more in the form of a question in my reply to your next comment.
I agree.
The state that you describe is merely "acting instinctively" (without interference from our prefrontal cortex).
Instinctively = Naturally
Being the case, coupled with the meddling of intellect as it runs unchecked in most people, the question that quickly positioned itself to me years ago was then who placed the intellect within us, guiding its imprint on the masses to cast its spell(ing) to enslave? And to what goal? Once one sees these positions the questions manifest by the tool of enslavement (intellect).
To what end, who knows. It all comes across almost as a game by beings whose motives and purpose would be unknowable, especially given all the intricacies that make up what we do and experience that obscures being awake/aware.
This has been a most interesting discussion with you. I've had most of these discussion during my life since a young age with either books pointing at these things, and the many different thoughts/spells (intellect) that cascade in front of myself, the witness. You do me much honor engaging on this most difficult topic that most would find bizarre and perhaps maddening, to be avoided. Thank you.
Conventional Wisdom would lead us to believe that "intellect" is "required for survival".
Conventional Wisdom would lead us to believe that a seven year old, abandoned in the forest, could NEVER survive for more than perhaps a couple of days at most.
I admire your fearlessness.
