But dance can be like meditation in another way, if the dancer is able to enter a flow state, she can escape judgement from her rational brain and fully be in the moment. In Arabic dance, this flow state is called Sultana and is related to Tarab, the ecstacy that can come from being moved by the music. You can learn more about these from Sahra's article on her Journey Through Egypt site.
Learning what you know is helpful to create confidence, and systematically learning helps to speed up the process for those of us who didn't grow up in the culture, but ultimately you want to improvise and give yourself over to the feeling in the moment, so more formalized pedagogy has to be balanced with putting in the time to absorb it all into your bones to the point beyond consciousness.
You also have to, when performing with this goal, be able and willing to detach from judging your moves or artistic choices during the dance. You can always look at film later, but you can't change it in the moment without disrupting the flow anyway, so allow yourself to let it go.
