"You don't use spirits to produce taps," she said; "see here." She put her hand over my head, not touching it, and I heard and felt slight taps on the bone of my skull, each sending a little electric thrill down the spine.

She then carefully explained how such taps were producible at any point desired by the operator, and how interplay of the currents to which they were due might be caused otherwise than by conscious human volition.

It was in this fashion that she would illustrate her verbal teachings, proving by experiment the statements made as to the existence of subtle forces controllable by the trained mind.

The phenomena all belonged to the scientific side of her teaching, and she never committed the folly of claiming authority for her philosophic doctrines on the ground that she was a wonder-worker.

And constantly she would remind us that there was no such thing as "miracle"; that all the phenomena she had produced were worked by virtue of a knowledge of nature deeper than that of average people, and by the force of a well-trained mind and will; some of them were what she would describe as "psychological tricks," the creation of images by force of imagination, and in pressing them on others as a "collective hallucination"; others, such as the moving of solid articles, either by an astral hand projected to draw them towards her, or by using an Elemental; others by reading in the Astral Light, and so on.
