shooting language

The drawing below is a representative sample of the drawing style of the Korwa people, a tribe from the state of Madhya Pradesh, in India. For these people, drawing seems to have been a revelation, a kind of mystical connection between image and meaning -- for at the time of this drawing, it was remarked that they spoke a language without written form. 

How would it be to revisit the engagement of the senses in trying to communicate with line and mark, instead of with voice and cadence? What kind of relationship would we have with the end product, how would our opinions of the process differ?
