Every night, before you sleep, affirm: “The Heavenly Father is with me; I am protected.” Mentally surround yourself with Spirit and His cosmic energy. Chant “Aum” three times, or the word “God.” That will shield you. You will feel His wonderful protection. Be fearless. That is the only way to be healthy. If you commune with God His truth will flow to you. You will know that you are the imperishable soul. - Paramahansa Yogananda.
