XXXVIII: “Lauded be Thy name, O Lord my God! I testify…”

“I beg of Thee, O my God, by Thy most exalted Word which Thou hast ordained as the Divine Elixir unto all who are in Thy realm, the Elixir through whose potency the crude metal of human life hath been transmuted into purest gold, O Thou in Whose hands are both the visible and invisible kingdoms, to ordain that my choice be conformed to Thy choice and my wish to Thy wish, that I may be entirely content with that which Thou didst desire, and be wholly satisfied with what Thou didst destine for me by Thy bounteousness and favor. Potent art Thou to do as Thou willest. Thou, in very truth, art the All-Glorious, the All-Wise.”
