V. Plant, Animal, Man

In the animal organism, in the waking stage, the separation and formation of what is excreted, as well as the excretion of the sentient substance, stand under the influence of the astral activity. In man there is added the activity of the ego organism. In sleep the astral and the ego-organism are not directly active. But the substance has been taken hold of by their activity and continues in it as though by inertia. A substance once formed through and through as occurs by the workings of the astral and ego-organization, will go on working in the way of these organizations in the sleeping state, as it were, out of inertia.
