Sanskrit Verse
निजगन्तुमनोभवाः रोगाः।
— (Ashtanga Hrudayam, Sutrasthana 1/21 - Interpreted)
Explanation
Ayurveda classifies diseases into three main types based on their origin: 1. Nija (Endogenous), which arise from an internal imbalance of the doshas. 2. Agantuja (Exogenous), which are caused by external factors like injury, trauma, or infections. 3. Manasika (Psychological), which originate in the mind due to imbalances of Sattva, Rajas, and Tamas.
Clinical Importance
This classification helps in determining the primary line of treatment. While Agantuja rogas (like a fracture) require immediate physical intervention, Nija rogas require internal dosha-pacifying treatments.
