The concept of Shen in TCM is often translated into English as "spirit." Yet the term "spirit" is limited in relation to the vastness of the term Shen. Shen includes mental alertness, mental sharpness, the ability to respond and reason, and most everything related to mental function, including the sub-conscious and conscious mind. Shen is housed by the Heart. When Shen is Deficient, sadness and depression will often result. Disturbed Shen can result in disturbing dreams, over-active dreaming, poor memory, restlessness, mania, and insomnia. Practitioners observe the quality of Shen in the clarity and focus of the eyes.
