In Chinese medicine, [Shen] may be though of as vitality of consciousness, or spirit. A person with strong and balanced [Shen] 'shines with personal presence': has force of personality, the ability to think, discriminate and choose appropriately. [Shen] is stored in the [Heart], which is the lower of the two houses of [Shen]. The higher house is the third eye, or forehead [chakra], where it brings forth clarity of thoughts and a conscious life direction. People with [Shen] disharmony have difficulty relating to their environment or have unreasonable responses to it.
