To the subconsciousness thus belongs the physical body, through which all spiritual organs more or less function. This organic function is thus in reality an extension of the function of the superconsciousness. And it is this part of the living being that is accessible to sensory perception. This extension constitutes not only the being's physical body, but also its psyche or mentality through which the experience of life or the manifestations are being sensed and perceived. We have expressed as the living being's "day-consciousness" this function of cognition. But the unfinished being has also a state of experience in which it is not conscious, namely its state during sleep. We have expressed this state as the living being's "night-consciousness". The night-consciousness is thus a state of experience in which the being finds itself when its physical body does not function, is at rest. Then the being's experience takes place on the so-called "spiritual plane", which exists beyond the physical plane of experience. Since the state of the being's memory on the physical plane of existence is, however, not intended to transfer memories from its night-consciousness to its day-consciousness, the beings on the mentioned plane have no memory about their experiences during its night-consciousness. The unfinished or still cosmically unconscious human beings are therefore wrong when they believe that they are unconscious during their night-consciousness. That is the reason why the doubt about immortality arises, when they see that a fellow being's physical body has become a "corpse". They do not understand that the living being can live without a physical organism. They do not know their own immortal I and their equally immortal superconsciousness with which this I is identical. We shall, as already mentioned, return to these primary subjects in later explanations of the symbols.
