What does Health Mean?

According to World Health Organization, health means a state of complete physical, mental and social well-being, not merely absence of disease or infirmity. With reference to traditional Tibetan Medicine, health means a balanced state of the three principle energies.  

Going in-between lines of these two disciplines, traditional system seems to be more holistic as it encompasses energy levels, which is beyond the cellular explanation of modern science.  The concept of mental well-being may imply the ability of the mind to function normally, though the mind full of negative emotions such as hatred, delusion and attachment.  Therefore, health is also a state of complete spiritual well-being.

Spirituality largely deals with the way we think, not how the mind is well-being. There is a suitable question which determines the state of your spirituality. Is the glass half full or half empty?

When you say the glass is half empty, you are well mentally but not spiritually. Sticking to the points, when you feel angry, you are well mentally but not spiritually. 

The definition for health given by WHO is a hyponym of complete health definition.
