Question: What is the spiritual root of dance?
Answer: Dancing in a circle where people hold hands symbolizes that in a circle all are equal. And this is its spiritual root.
Holding hands symbolizes our mutual connection and the circle shows equality and wholeness, since in our world there is no image more complete than a circle or a sphere. So men dancing in a circle is derived from spiritual roots.
With my teacher, Rabash, the students danced only in a circle, holding hands. Moreover, they always went around from right to left, counter clockwise, because the right line comes first, and after that the left line, and then the middle line.
Sometimes individuals would enter the center of the circle and dance within it. This symbolized that precisely within the circle a person can feel a unique spiritual state. All the other kinds of dances belong to modern forms and don’t have spiritual roots.
