Prana is a concept from ancient Indian philosophy that refers to the vital life force or energy that flows through all living beings. It is believed to be the source of vitality and health, influencing physical, mental, and spiritual well-being. In practices like yoga and Ayurveda, prana is often associated with breath and is thought to be essential for maintaining balance in the body. In yogic traditions, prana is divided into five main types, known as pranayama, which govern different physiological functions. These include apana (downward energy), udana (upward energy), samana (digestive energy), vyana (circulatory energy), and prana (inward energy). Understanding and harnessing prana is considered vital for achieving harmony and health.
