Krishna now explains the third and final syllable of the sacred formula: Sat. This word carries multiple layers of meaning, each pointing to an aspect of the ultimate reality.

Sadbhaave — in the sense of existence or reality. Sat means “that which is” — being itself, pure existence. In Indian philosophy, Brahman is described as Sat-Chit-Ananda — existence, consciousness, and bliss. Sat is the foundation: the unchanging, indestructible reality that underlies all appearances. When we say something is “sat,” we mean it is real, true, genuinely existent rather than illusory or temporary.

Saadhubhaave — in the sense of goodness. Sat also carries a moral meaning. A sat-purusha is a good person, a righteous person. Sat-karma is good action. This connects truth and goodness: what is genuinely real is also genuinely good. The deeper one penetrates into reality, the more one encounters goodness. Evil, in this framework, is a distortion of reality — a departure from what truly is.

Prashaste karmani — in auspicious action. Sat is also applied to actions that are praiseworthy, beneficial, and aligned with dharma. A marriage ceremony, a sacred offering, a selfless act of service — these are described as “sat” because they participate in the deeper goodness of reality.

By explaining these three meanings, Krishna reveals that Sat is not just a word but a philosophical declaration: reality, goodness, and right action are ultimately one. To act in accordance with Sat is to act in accordance with the deepest truth of the universe.
