Pranayama is an ancient yogic practice that focuses on the regulation of breath to control the flow of prana, or life force, in the body. The word "Pranayama" is derived from two Sanskrit words: "prana" meaning "vital life force" or "energy," and "ayama" meaning "extension" or "expansion." Together, Pranayama refers to breathing techniques that enhance physical, mental, and spiritual well-being by balancing energy in the body.
