Let me firstly clarify the intent of this thread - simply to provide my perspective on Qi/Chi and what basis in reality it may have, and hear a few of yours. A few simple facts should make even the harshest skeptic at least take a second glance towards the possibility of any merit in the concept. Qi, whether you believe it to be what traditional definitions claim it as or not, is simply a term for an energy in the body. Human beings have the most complex electrical structure yet found in the known universe resting inside their skulls. This electrical structure (brain) functions as a computer for further electrical structure that extends throughout the entirety of the body, multiplying this complexity exponentially if you view the entire nervous system as one entity. Atoms from an object never truly touch the atoms from another object, it's all an interaction of electrical fields. While none of this is by any means "hard evidence", we do know that there IS extraneous energy in the human body, and we only have one control center for it, which we barely understand, and can barely interface with. Meditation, and essentially every principle of IMA deals in an interaction with the brain's indirectly accessible regions. We have the power lines, and the power plant, but refuse to believe anybody who claims to have lit the bulb. Hell, if you want to bring in theoretical physics, from a quantum perspective the action your opponent has taken, is taking now, and is about to take all exist at once and eternally, as the energy has already been exchanged at a different point in time (which already exists as time is static, not linear). Who's to say your brain is limited in its perception? Maybe sometimes somebody really can feel the next move of an opponent (without a lot of chi sao experience, lol.) Quantum particles aren't bound by the laws of space or time, and with all the electrical energy firing around our brains, that means your thoughts aren't either. From an objective standpoint, the neurological impulse telling my body to throw a punch in my next fight already exists in space-time. Our perceptions of time are like our perceptions of light, taken in and then processed in a way we can understand. We simply know more about the lens of the eye than the "lens" through which our minds control time perception. To what degree we subconsciously probe into or are aware of the extraneous outside our own perceptions of time is completely unknown. **Note: Muscular coordination has a major part to play in strength, many forms of meditation that verge more on intense focus will recruit additional muscular tissue, and promote coordination.
