IN SHORT A sacred sound can steady you and remind you of deeper purpose.
The chapter turns from sorting acts to hallowing them: the ancient triple name of the Absolute. Every sacred tradition needs words that carry the whole — Om Tat Sat is the Vedic shorthand for ultimate reality. The next three verses unpack each syllable. It is like an official government stamp with three seals that makes every office paper valid.
