Being spontaneous means simply answering back. Those who are skillful in improvisation in music or dance say their actions are merely dictated by the structure of their experience. Space awareness shows us that the same is true for ordinary experience. Spontaneity is not wildness. It is taking responsibility for what is already there.
Total involvement is the key to developing the proper motive.
Though many of us romanticize a state of being open to the full play of our senses, in fact our relationship to our sense is based on deep-seated ambivalence. Ambivalence is based on not fully wanting to be at any given point. We may feel we need to drive the car, bur we don't want to do it totally. We have no place to hang out, no snug cocoon. This is why space awareness exercises have an outrageous quality.
