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.
