In 1881 Doctor Kingsford delivered in London, before drawing-room audiences, comprising representatives of literature, art, fashion, and the peerage,--audiences inclusive of the most notable people in London, the nine lectures that are published under the title of "The Perfect Way," and at the time these lectures inspired a profound interest. Their central theme is the Pre-existence and Perfectibility of the soul. "The intuition," she says, "is that portion of the mind whereby we are enabled to gain access to the interior and permanent region of our nature, and there to possess ourselves of the knowledge which in the long ages of her past existence the soul has made her own. For that in us which perceives and permanently remembers is the soul. And all that she has once learned is at the service of those who duly cultivate relations with her." And those relations, she taught, are cultivated by living so purely in thought and deed as to prevent the interposition of any barrier between the phenomenal (or the outer) and the substantial (or the inner) self; and by steadfastly cultivating harmonious relations between those two, by subordinating the whole system to the Divine will,--thus does one gain full access to the stores of knowledge in the soul. Doctor Kingsford further explains:-- "For, placed as is the soul between the outer and the inner mediator, between the material and the spiritual, she looks inwards as well as outwards, and by experience learns the nature and method of God; and according to the degree of her elevation, purity, and desire, sees, reflects, and transmits God. It is in virtue of the soul's position between the worlds of substance and of phenomenon, and her consequent ability to refer _things_ to their essential _ideas_, that in her, and her alone, resides an instrument of knowledge competent for the comprehension of truth, even the highest, which she only is able to behold face to face. It is no hyperbole that is involved in the saying, 'The pure in heart see God.' True, the _man_ cannot see God. But the divine in man sees God. And this occurs when, by means of his soul's union with God, the man becomes 'one with the Father', and beholds God _with the eyes of God_.... "And he to whom the soul lends her ears and eyes, may have knowledge not only of his own past history, but of the past history of the planet, as beheld in the pictures imprinted in the magnetic light whereof the planet's memory consists. For there are actually ghosts of events, manes of past circumstances, shadows on the protoplasmic mirror, which can be evoked.
