The Mantra is the essence of sound or it is the embodiment of truth in the form of sound. The mind rides on the subtle energy of the breath. The Prana is the factor that purifies the subtle channels of the body. So when you chant a Mantra, you are charging your breath and energy with the energy of the Mantra and so working directly on your mind and subtle body. The 'Guru' of master who gives the Mantra has repeated it himself for a long time, during the course of his spiritual practice. He also has realized the power of the Mantra and is able to charge it with a living conscious force. When the Guru has made his Mantra divine and alive that Mantra is perfect, it brings liberation, and also bestows all types of powers.
