(LARGE PRINT EDITION) 1926. Hall, the American philosopher, in over a period of 20 years of dynamic public activity, has steadfastly sought recognition of the belief that world civilization can only be perfected when human beings meet on a common ground of intelligence, cooperation and worthy purpose. The Mystery of Fire originally appeared under the title Melchizedek and the Mystery of Fire. In this essay, Hall clearly sets forth the relationship of the fire symbols to the life forces within the human body. Special treatment is given to the subjects of the ductless glands and the part which they play in the development of spiritual consciousness.
