For each human soul, there is a unique, constant value of “a.” The imaginary index “b,” however, is continuously variable. . . . At end of life, the soul abandons its complex eigenvalue and assumes a new wave form whose eigenvalue is real. . . . This change is known to be accompanied by conformal transformation, but . . . there’s disagreement about the details. —JOHN W. CAMPBELL, “ON THE NATURE OF ANGELS”
