As the Saturn evolution progressed, facts follow of a different kind from those already related. Whereas everything hitherto was a reflection of outer life and feeling, there now begins a kind of inner life. In the Saturn world a life of light begins flickering here and there, and growing dim again. A quivering glimmer is seen in some places, something like flashes of lightning in others. The Saturn heat bodies begin to glimmer, to sparkle, and even to emit rays. This stage of evolution having been reached, there again arises the possibility for certain beings to develop their activity. They are those known to occult science as “Sons of Fire.”(15) Although these beings have an astral body, they are unable at his particular stage of their existence to stir their own astral bodies; they would not be capable of any feeling or emotion unless they could act upon the Saturn heat bodies which have attained the stage of evolution described. That action affords them the possibility of recognizing their own existence from the effect which they produce. They cannot say to themselves, “I am here”; but rather, “My environment causes me to be here.” They have perceptions, and what they perceive is the light-effects in Saturn which have been described. These are, in a certain manner, their ego. This gives them a peculiar kind of consciousness. It is designated “picture-consciousness.” It may be represented as having the nature of human dream-consciousness, except that the degree of activity it enjoys must be imagined as being very much greater than it is in human dreams, and also that it is not a question of shadowy dream-pictures floating hither and thither, but of pictures that have a real connection with the play of light on Saturn.
