In referring to the existence of the etheric body and its conscious perception, we must distinguish two methods of approach. There is of course that inner process which leads to genuine clairvoyance, by way of meditation. And there is also an educative process working from outside. If we take the trouble to see and estimate the processes of nature aright, we shall acquire a visualization of these things which is based on judgment. The actual organs of clairvoyance must be developed from within; but judgment is developed in contact with the world outside ourselves. If we develop the finer shades of judgment in the external world, this highly evolved judgment will come toward that more intimate process which passes outward from within, in meditation.
The blue phantom is that physical framework within the organism which tends to exuberate unduly. Its normal form is associated with the formation of the ear. Educate yourselves, train yourselves in the study of man so far as to have regard to this ear organization and especially its interiorization, and at the same time to the characteristics of the organ of sight. Then remember that the process of sight occurs in the etheric, the process of hearing in the air. This is a considerable difference. All that lies comparatively low in the ascending scale of ponderable and imponderable is associated and linked with the more deep-seated organs and functions in the interior of man's organism. All that is more akin to the etheric and imponderable is situated toward the surface and periphery.
