Sanskrit Verse

कालार्थकर्मणां योगो हीनमिथ्यातिमात्रकः। सम्यग्योगश्च विज्ञेयो रोगारोग्यैककारणम्॥

— (Ashtanga Hrudayam, Sutrasthana 1/19-20)

Explanation

This triad represents the fundamental causes of health and disease. Roga (disease) is caused by the Heena (deficient), Mithya (improper), or Ati (excessive) yoga (conjunction) of Kala (time/seasons), Artha (objects of sense organs), and Karma (actions of body, mind, and speech). Arogya (health) is caused by their Samyak Yoga (balanced or proper conjunction).

Clinical Importance

This is a more detailed classification of Hetu (cause). For example, Ati-yoga of Artha is looking at very bright light; Mithya-yoga of Karma is suppressing natural urges. A physician diagnoses disease by identifying which of these conjunctions has occurred.
