Vayus, in the context of yoga and Ayurveda, refer to the five vital winds or energies that govern various physiological and psychological functions within the body. These include Prana (life force), Apana (downward force), Samana (digestive energy), Udana (upward force), and Vyana (circulatory energy). Mastery of the Vayus through practices like pranayama and meditation is believed to enhance overall well-being and spiritual development.
