According to Colour Therapy, all the diseases can be classified on the basis of causes of diseases into two groups:

A) Diseases Resulting from Our Living Style: When we live in dark, congested, unhygienic and unfavorable atmosphere, our body becomes a target of disease of all sorts.

B) Diseases Resulting from Our Thinking Pattern: Diseases due to dubiety, uncertainty and whimsical approach of thinking, i.e., our emotional attitude, mental tension, strain, materialistic approach, insecurity and our ignorance about the spiritual knowledge are causes of these types of diseases.

As is clear, if any one interested in living a disease free life he should take care of his life style and his thinking pattern in the light of above mentioned discussion.
