Psycho-Spiritual Components

To smell the joy and beauty of life, affects the mind and spirit. Picking up an odor is not just a physical experience, it is a mental and spiritual activity as well. This point is about newness, and the ability to receive new experience. A fragrance can evoke memories of the past; old experience can be remembered without living in the past. [JRW]

Energetically, the function of LI-20 relates to the receptive qualities of the metal element and the functional connection between the large intestine and the lung officials. The sense of smell is one of the most important ways in which the reality of posterior heaven is transmitted to the internal world. In this regard it is important to note the olfactory nerve terminates in an area of the brain directly related to human emotion (the limbic system). Additionally, one’s sense of smell contributes in a large way to the way things taste. Hence, LI-20 and ST-1 may be considered to provide significant input into the process by which alimentation and respiration support the fires of ming men through nurturing the jing of posterior heaven. The TCM functions of this point are to open the nasal passage and disperse wind and eat. Here, wind and heat arise from the inability to properly digest life and eliminate that which has lost its essential value. [LJ]
