"In the chapter entitled “Swimming on Land” from my Thirteen Treatises, I spoke of envisioning the air we breath to be like water. Water can swirl and accumulate into a powerful force--its insubstantiality waxes into substantiality. Conversely, if we can imagine a powerful opponent as inconsequential as a puff of air, we can make his substantiality wane into insubstantiality."
