A “Mantra” may generally be considered as a sacred set of words and thoughts communicating an invocation or prayer. a mantra could also be just some syllables, for example, Beej-Mantra or Seed-Mantra.
Mantras originated in Hinduism and were later adopted into other eastern beliefs in Buddhism, chiefly in Tibet, mainland China, japan and other Asian countries.
There are 2 main ways to invoke a Mantra.
A Mantra is typically repeated or chanted 3, 108, or more times, usually in multiples of 9. The chanting should be done in basic tone. Specific hand-gestures are used with specific sounds. Scriptures of Sam-Veda and Natya-Shastra (by Sage Bharat Muni) codified the sounds, music, and drama.
In the recent times, a lot of Mantras are sung musically.
In a musical form, a Mantra can be considered as a kind of performing art.
As mentioned above, using a Mantra is more of a kind of Performance Art than Performing Art.
In the Western mysticism, chantings have been used, independent of the concept of Mantra.
