MANTRA

Chants or Mantras have been analyzed to be energy-based sounds. Voicing them produces a physical vibration. Chants are hence, known to create thought-energy waves, making the being also vibrate in tune with the energized spiritual appeal of a chant. 

“The mantra can not only create new subjective states in ourselves, alter our psychical being, reveal knowledge and faculties we did not before possess, can not only produce similar results in other minds than that of the user, but can produce vibrations in the mental and vital atmosphere which result in effects, in actions and even in the production of material forms on the physical plane.” - Sri Aurobindo
