Qi-gong of Sato method was studied by means of several physical technique in order to measure biophysical changes brought upon by transition of conscious states caused by Qi-gong operation. Measurements used are a single square voltage pulse method (SSVP), near-infrared photometry, thermography, accelerated plethsmograph and EEC. It was clarified that when Qi-gongist operates Qi to switch over to different Qi-level his sympathetic nerve was excited at hand, and in his brain blood flow increased at first and then exhibited a moment of deficiency of oxygen. The Qi-receiver was observed to be affected by Qi-operation but not quite synchronously, judging from the measurement with SSVP. The EEG of the Qi-gongist showed strong α_1 wave, indicating relaxed state throughout all the different Qi-levels. On the other hand, Qi-receiver's EEC showed relatively strong coexistence of θ and β wave especially in L7. The characteristics of Qi-level appeared clearly in APG index and temperature of both Qi-gongist and Qi-receiver with the same tendency. That is, in L1 state temperature raised and APG index was low, whereas in L7 state temperature was relatively low but APG index was high. In the L7 state many subjects mension about floating and comfortable or sometimes extension feeling to the universe. These sensation is together with above noted facts.
