As you read Georgiana's answers, make note of when she refers to expression and when she refers to manifestation. Expression is an ideal; the "perfect" expression before it becomes manifest (for example the second person of the Trinity). Manifestation is the "physical expression" into the relative realm. Even though we are taught in Metaphysics the concept of "Mind, Idea, Expression" we see that Georgiana and other writers seem to imply a process of "Mind, Expression, Manifestation."
