Sanskrit Verse
व्यानो हृदि स्थितः कृत्स्नदेहचारी महाजवः। गत्यपक्षेपणोत्क्षेपनिमेषोन्मेषणादिकाः। प्रायः सर्वाः क्रियास्तस्मिन् प्रतिबद्धाः शरीरिणाम्॥
— (Ashtanga Hrudayam, Sutrasthana 12/7)
Explanation
Vyana Vayu is located in the heart and circulates throughout the entire body with great speed (Mahajavah). It is responsible for all movements, such as locomotion (Gati), extension (Apakshepana), flexion (Utkshepana), and the blinking of eyelids (Nimesha-Unmeshana). Nearly all bodily actions are dependent on it.
Clinical Importance
Vyana Vayu governs the circulatory system, nerve impulses, and muscular movements. Its imbalance can lead to systemic diseases, circulatory problems, and neurological movement disorders.
