“Be assured, we shall not go to Canossa, either bodily or spiritually.”

Variant translation: Close your bodily eye, that you may see your picture first with the eye of the spirit. Then bring to light what you have seen in the darkness, that its effect may work back, from without to within.

Context: Close your bodily eye, so that you may see your picture first with the spiritual eye. Then bring to the light of day that which you have seen in the darkness so that it may react upon others from the outside inwards. A picture must not be invented but felt. Observe the form exactly, both the smallest and the large and do not separate the small from the large, but rather the trivial from the important.

Ein Volk, damit es sich geistig freier ausbilde, darf nicht mehr in der Sklaverei seiner körperlichen Bedürfnisse stehn, nicht mehr der Leibeigene des Leibes sein. Es muß ihm vor allem Zeit bleiben, auch geistig schaffen und geistig genießen zu können.

Address to the Society for Psychical Research (1897)
Context: Popular imagination presupposes spiritual beings to be utterly independent of gravitation, while retaining shapes and proportions which gravitation originally determined, and only gravitation seems likely to maintain.
When and if spiritual beings make themselves visible either to our bodily eyes or to our inward vision, their object would be thwarted were they not to appear in a recognizable form; so that their appearance would take the shape of the body and clothing to which we have been accustomed. Materiality, form, and space, I am constrained to believe, are temporary conditions of our present existence. It is difficult to conceive the idea of a spiritual being having a body like ours, conditioned by the exact gravitating force exerted by the earth, and with organs which presuppose the need for food and necessity for the removal of waste products. It is equally difficult, hemmed in and bound round as we are by materialistic ideas, to think of intelligence, thought, and will existing without form or matter and untrammeled by gravitation or space.
