Pneuma is a Greek word that means breath or spirit. It's often used to describe the vital life force that animates living beings. To convey the same idea, there are several synonyms that can be used. For instance, the word "chi" is used in Eastern traditions to describe the same energy, while "prana" is a similar concept in yoga and Ayurveda. The word "mantra" refers to a sacred sound or word that channels spiritual energy. The term "breathwork" is also used to describe practices that use deep breathing to access the pneuma or spirit energy within. Ultimately, these synonyms all point to the same idea of a vital, animating force that pervades all living beings.
