Why Chen's
Peace
Forth Principle: Listen
Listening energy is extremely important for Chen Taiji. Shrouded in mystery, listening energy is rarely conveyed verbally. New students are left to their own devices to discover what to listen for. It's a weeding-out process where those talented enough to grasp Chen's finally close their eyes and experience Synesthesia:
"a perceptual phenomenon in which stimulation of one sensory or cognitive pathway leads to involuntary experiences in a second sensory or cognitive pathway."
