Here is the law: “I am that which I feel myself to be.” Practice changing the feeling of every day by affirming: “I am Spirit; I think, see, feel, and live as Spirit, the Presence of God.” (The other self in you thinks, feels, and acts as the race mind does.) As you continue to do this, you will become one with God. As the sun in the heavens redeems the Earth from darkness and gloom, so will the realisation of the Presence of God in you reveal the man you always wished to be—the joyous, radiant, peaceful, prosperous, and successful man whose intellect is illumined by the light from above.

Born on May 20, 1898, Joseph Murphy was an Irish born, American author and New Thought minister. In his twenties, before being ordained a priest, an experience with healing prayer led him to leave the Jesuits and move to the United States, where he became a pharmacist in New York City. Here, he attended the Church of the Healing Christ. 
Murphy traveled to India and spent lot of time with Indian sages, learning Hindu philosophy. In the mid-1940s, he moved to Los Angeles, where he met Religious Science founder Ernest Holmes. He also taught at the Institute of Religious Science in Los Angeles. He became the minister of the Los Angeles Divine Science Church in 1949, which he built into one of the largest New Thought congregations in the country.
Some of his notable works include: Your Infinite Power to Be Rich (1966), The Cosmic Power Within You (1968), The Healing Power of Love (1958), Stay Young Forever (1958), Wheels of Truth (1946), Supreme Mastery of Fear (1946), etc.
