This document discusses the concept of "reverse breathing" in t'ai chi ch'uan and seeks to clarify misunderstandings that can arise from translations over millennia. The author explains that reverse breathing naturally occurs through proper body mechanics rather than forced actions. Specifically, inhaling slightly contracts the abdominal wall during certain foot and leg movements, while exhaling allows a passive expansion of the body during transitional movements. Direct instruction is needed to properly understand without forcing or misinterpreting the technique.
