Art is the meeting of mind, body and heart. The existence of art relies on the collaboration of all three. Nothing can dominate over the others or the imbalance will shift the art into a mere exercise.
Whole body dancing would be reduced to movement on command.
Full lung-ed singing would turn into noise.
Hands to keyboard typing an inspired story devolves to empty tapping.
However, art starts as mere exercise. It is the practice of bringing together mind, body and heart over and over again that we can finally actually create our art.
