<div style="text-align:justify;">[[Nidana Sthana]], the second section within [[Charaka Samhita]], is about creating a strategy for diagnosing disease on the basis of history of causative factors and clinical examination. The study is comprehensive and is different from modern medical system to guide a physician to diagnose and treat disease with minimal use of laboratory, imaging and other tools.

''Ayurvedic'' diagnosis has two parts - the first being an evaluation of the self-healing capacity of the body which depends upon equilibrium of five components, namely ''doshas'' (body humors), ''agni'' (digestive and metabolic capacity), ''dhatu'' (body tissues), ''mala'' (waste) and psycho-spiritual state. Health is a state of equilibrium, whereas disease is a state of dis-equilibrium of any of these factors. According to ''swabhavoparam vada'' (theory of natural resolution), the resolution / destruction of the existing always happen naturally in the course of time. (Cha.Su.16/27) So the nature itself heals disequilibrium. This aspect of host defence mechanism is important to be assessed for knowing natural healing capacity of an individual. In the fourth chapter of [[Nidana Sthana]], [[Prameha Nidana]], the process of interaction between aggravating and pacifying factors  to cause disease is described. If the host defense factors are stronger than aggravating ones, then the disease will not occur and vice versa. Therefore, before making diagnosis of a disease, it is important to examine patient first with emphasis on his ''prakriti'' (basic constitution), ''sara'' (quality of tissues) etc. Every person has a unique constitution and hence the same biological investigations cannot be precise to assess his health status completely. Personalized assessment is important to diagnose normal and abnormal state of the individual.
