The Holy Spirit is not a form. Devotion is not directed to a teacher or image. Give each day to the Holy Spirit. Ask the Holy Spirit for the miracle of experiencing perfect equality with everyone you meet. Giving yourself over to the practice of the ACIM lessons can be a devotion. Pray and follow guidance. God is not a personality. The way to worship God is to practice forgiveness and be as God created you. Be peaceful. See your Self beyond the body.
