That's interesting. im not too familiar with TCM but I have looked into yogic and Taoist teachings in the past. According to the taoists each one of the primary internal organs relates to a specific emotion and they teach that emotions can be regulated by focusing on the corresponding organs. they also suggest that emotional imbalances can manifest in those organs and vice versa.

Both the yogis and the taoists believe that the etheric body is interweived into the meridians and organs of the body and according to the Sufis the cavity of the chest around the heart contains the etheric preceiver. Having said that, the chinese hare stimulated research into the "Second brain" or the belly with promising scientific results.
