Sanskrit Verse
सहजं कालजं युक्तिकृतं च बलमिति।
— (Charaka Samhita, Sutrasthana 11/36)
Explanation
Bala means strength, immunity, or vitality. Ayurveda describes it in three types: 1. Sahaja Bala (Congenital or hereditary strength, determined by Prakriti and Dhatu Sara), 2. Kalaja Bala (Temporal strength, which varies with season and age), and 3. Yuktikrita Bala (Acquired strength, which is developed through proper diet, exercise, and rejuvenative therapies).
Clinical Importance
Assessing a patient’s Bala is crucial for determining their prognosis and the intensity of the treatment that can be administered. While Sahaja Bala is innate, a physician’s goal is to maximize the patient’s Yuktikrita Bala through Rasayana and other therapies.
