A Vedantic assertion meaning “I am That (Brahman)” or “The immortal spirit is I.” Etymologically, it comes from sah, meaning “He,” and aham, meaning “I.” According to the yogic tradition, with every inhalation and exhalation of the breath we are unconsciously pronouncing this famous mantra—this ajapa mantra (spiritual phrase uttered silently) is continuously and unconsciously pronounced throughout the entire life of every being.
