Nidana section studies diagnostic principles in view of two important aspects like knowledge of roga (disease) and rugna (patient). It always considers interaction between the individual and the affecting pathological entities. It also considers the prognosis and inter-relation of different diseases or co-morbid conditions.

===Knowledge of the individual===

The first being an evaluation of the self-healing capacity of the body which depends upon equilibrium of five components, namely [[dosha]] (regulatory functional factors of body and mind) , [[agni]] (digestive and metabolic capacity), [[dhatu]] (body tissues), [[mala]] (metabolic waste products) 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]], the resolution / destruction of the existing always happen naturally in the course of time. So the nature itself heals disequilibrium.[[Chikitsaprabhritiya Adhyaya#Swabhavoparama vada (theory of natural destruction)|(Cha.Su.16/27)]] This aspect of host defence mechanism is important to be assessed for knowing natural healing capacity of an individual. In the fourth chapter,[[Prameha Nidana]], [[Prameha Nidana#Process of Onset of Disease|the process of onset of disease]] through interaction between aggravating and pacifying factors is described [[Prameha Nidana#Process of Onset of Disease|(Cha.Ni.4/4)]]. 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, [[Rogabhishagjitiya Vimana#Examination of patient|examination of patient]] is important with emphasis on his [[prakriti]] (basic constitution), [[sara]] (quality of tissues) etc described in context of [[Rogabhishagjitiya Vimana#Examination of patient|ten fold examination of patient(Cha.Vi.8/94-131)]]. 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.

Before knowing disease, one need to know the self-healing capacity of the human being. This depends upon equilibrium of five components of health, namely [[dosha]] (regulatory functional factors of body and mind) , [[agni]] (digestive and metabolic capacity), [[dhatu]] (body tissues), [[mala]] (metabolic waste products) and psycho-spiritual state. Health is a state of equilibrium, whereas disease is a state of dis-equilibrium of any of these factors.
