How do we cultivate inner stillness, powerful healing presence, mastery of medicine (perhaps even with a capital “M”) beyond technique, or whatever you want to call it? We were playing with concepts like “concentrating the yì (intent) and unifying the shén (spirit/s), to stop the jīng essence and Qì from separating, …so as to gather in the (patient’s?) jīng (essence)” 專意一神，精氣不分…以收其精 (Lingshu 9). In this context, Leo mentioned the phrase 搖精 yáo jīng, which I have, somewhat fancifully, translated in the title of this short article as “jingling jīng,” but which you could also render as “rattling the essence.”
