The third section of the Charaka Saṃhitā, Vimana‑sthana, is a classical handbook of specific medical principles. Compiled from the ancient Agniveśa tradition and organized by Charaka (later redacted by Dṛḍhabala), it systematizes measures of health and illness: prognosis, strength (bala), lifespan, diagnostic criteria, drug potency and compatibility, and rules for dosing, diet and seasonal regimen. Key themes are individualized therapy (prakṛti and vikṛti), balance of the doṣas, preventive regimens, physician conduct and rational combination of remedies. Vimana‑sthana’s insistence on measurement, context and personalized care resonates today in lifestyle medicine, preventive health and integrative, patient‑centred approaches—bridging timeless wisdom with modern clinical thinking.
