5. Planes and Parts of the Being
No, subliminal is a general term used for all parts of the being which are not on the waking surface. Subconscient is very often used in the same sense by European psychologists because they do not know the difference. But when I use the word, I mean always what is below the ordinary physical consciousness, not what is behind it. The inner mental, vital, physical, the psychic are not subconscious in this sense, but they can be spoken of as subliminal.
