Mantra (Sanskrit मंत्र) means a sacred utterance, numinous sound, or a syllable, word, phonemes, or group of words believed by some to have psychological and spiritual power. Mantra may or may not be syntactic or have literal meaning; the spiritual value of mantra comes when it is audible, visible, or present in thought.
