I just have to say that these discussions are great. The internal arts section is the reason I joined. From what I understand (so far) about ki is that the example of the water condensing and the electrical charge are the closest examples of ki but not for the reasons they were brought up. Like Sam said, "energy" itself is not visible.... only its interaction [not reaction] with matter." Li*, or the physical manifestation of ki, what we percieve, feel, hear, see around us. For example; Ki : stress :: Li : ulcer. This also extends to inanimate objects as manifestations of ki albeit in their raw state. I would say "the ki of that chair" is less acurate than "the ki of that wood." I relate Morihei Ueshibas credo that ki is love to this by comparing love to connectedness and not "I love my mom." Keeping in mind that everything can be broken down to electrons, neutrons, protons and even smaller quarks (although I don't know much about quarks) helps to dissipate the mysticism of ki and anchor it firmly in the real world. Thinking in terms that everything is made of the same material/energy definetly helps to wrap my mind around the philosophical aspects that, in my opinion, are more important applications of ki than creating Star Wars-esque lightning. (I don't deny the possibility of using ki like the force, however I doubt the probability of anyone gaining that significant amount of control in one lifetime.) *I learned about this concept in Reflections on Qi by Gary Khor if anyone wants to check it out.
