The word “Mantra” has been derived from Sanskrit. Mantra contains two words – “man” which means “to think” (also in manas “mind”) and suffix “tra” which means “tool”, hence a literal translation would be “instrument of thought”. A mantra is a powerful word or phrase that may or may not have meaning in the same way as a sentence. Mantra is a religious or mystical syllable or poem, typically from the Sanskrit language. Mantras are primarily used as spiritual conduits, words or vibrations that inculcate concentration in the devotee. Mantras are also integrated in religious rituals to remove obstacles, avoid danger, reduce foes, or accumulate wealth. Mantras got their origin from the Vedas of India.
it can also mean “kindness” Usually used for being polite when requesting something or expressing thanks. (it is an Urdu word and may not be used by all Hindi speakers.)
