In all religion, people have used the repetition of prayers or mantras, which will help to reach or touch the higher consciousness. It invokes the power of the spoken word and the power of sound that framed the words. It was through this power that Joshua fought the battle of Jericho and the walls came tumbling down. It was through this science that Jesus raised Lazarus and cast out evil spirits. And through this power we can overcome darkness in our own world.
There are many mantras and prayers are used in all spiritual traditions of most religions in the world. The Buddhists sound the Om Mani Padme Hum, the Sufis chant the La Ila Ha Il Allah, and the Kabbalists recite the names of God, Adonai, Elohim, El Shaddai, and El Hai. The Hindus chant the Gayathri Mantra and the Catholics recite the Father in Heaven and Hail Mary.
All these prayers and mantras have wonderful power of healing the body mind and spirit, if recited with faith and a loving heart.
