If understood with sufficient depth and sophistication, I think the flow can be used as a direction for literally everything. In Daoism, the flow is, among other things, defined as being at the very center where the black - chaos - and the white - order - meet. Just at touching point.
Incidentally, that is reflected in neuroscience. The left hemisphere of the brain is your center of order, repetition, rules, routine, plans. The right hemisphere of the brain is your center of chaos, uncharted territory, creativity, birth, also emotionality. So Daoism describes physically integrating your both cranial hemispheres in a harmonic fashion. And then you are, automatically, on the right path, in a way.
Though I would add to that the cross to keep you really centered. Because this covers horizontal harmony. But what about vertical? For that, integrate the symbol of the cross. Its center stands for taking all the world's suffering upon yourself. It stands for taking responsibility, for taking it all in. For standing in the fire of suffering. And be reborn. And be centered. Calm. In the eye of the storm. Focused straight ahead. Not just metaphorically. But physically, in your brain.
The circle, and within it the cross. The globe, and within it the star. Holy. Wholesome. And at the same time centered. All dimensions are integrated, in balance and harmony. Perfection. Goodness, Truth, Beauty. The holy trias. And your brain activity can reflect that - or not. And because your brain reflects your environment, this will mean you will also be in tune with you environment. So in a way this is a tautology. But this is what philosophy and religion comes down to, IMO. And it is a real physical phenomena. The golden way.
The medicine man told me so in my dreams.
But neuroscience supports this image.
The only question is: How to get there.
Well, by integrating all there is to you. And I mean all of it. Everything. Including the shadow. And whatever lurks within it. It means opening your mind. It is, in its most perfect form, the Ubermensch. Still, though... how? Many ways lead to Rome, as they say.
One can be religion. Or meditation. Philosophy, though it can be rocky to get access that way, but it is there. Or having really great psychedelic experiences (though which likely will have to be earned beforehand in some manner or the other, so to be ready).
But weird, then, that something as "irrational" as religion would turn out to be so central to the human experience, then. Like, literally central. On a physical level. At least so my working hypothesis goes.
