Ayurveda is one of the greatest contributions by the sages to mankind. With strong and basic principles and time tested validated clinical evidences, Ayurveda is a symbol of truth. After finding out the basics of the universe, sages traveled long distances as part of the research to understand the relationship between universe and human body. They were finally able to draw a conclusion that human body is a part of the universe. Human body responds as per the changes in the universe. The positive response leads to a healthy body while negative response ends in diseases. The definition of treatment— rectification of the damages and problems created by the disease and re- tuning of the body in harmony with nature.
