The designer totally disappears as an ego. The designer surrenders to the ultimate. The source of the design is beyond the grasp of our minds. The source is the God itself or call it totality or atman or almighty. The designer becomes a vehicle for that ultimate energy to flow through him.
All beautiful arts come from the beyond.
A dancer completely dissolves in the dance and the dance continues. It is the dance of the ultimate itself. A painter totally disappears in the moments and just give strokes as if he is possessed by some great higher self. In that transcendental space, the dancer, or the painter or architect are in great joy. We can give so many examples.
