Etymology

The word "mantra" originates from Sanskrit, where "man" refers to the mind or thought, and "-tra" signifies an instrument. Thus, a mantra is literally a "tool for the mind"—a phrase or sound used to focus thought, often in spiritual or meditative practices. Over time, it broadened to mean any repeated phrase or guiding principle.
