A detailed and comprehensive study of the Great Invocation, a world prayer of dynamic proportions. The Great Invocation is one of the most beautiful and important prayers given to humanity at the close of World War II. It was released through the writings of Alice A. Bailey in three successive versions, culminating in the final version in 1946. It has many mystical purposes, one of which is to anchor, through human invocation, the healing powers of God's Love, Light, and Spiritual Will on Earth and defeat the forces of darkeness.
