Steiner describes Sorat in “Reading the Pictures of the Apocalypse“:
If one had written correctly with Hebrew letters (right to left) and then read correctly (also from right to left), the following would have resulted: 60, Samech, 6 Waw; 600 was written by esotericists as 200 + 400: 200 Resch + 400 Taw. Hence, we get 666, which in Hebrew letters spells “Sorat.” Sorat is also the corresponding word in Greek. Sorat has meant “Demon of the Sun” since ancient times. Every star has its good spirit — its intelligence — and its evil spirit — its demon. The adversary of the good powers of the sun is called Sorat. Christ was always the representative of the sun, namely, the intelligence of the Sun. Sorat is, then, the adversary of Christ Jesus. The sign for Sorat looks like this:
The sign of the intelligence of the Sun is the following:
This is, at the same time, the occult sign of the lamb. The lamb receives the book with the seven seals. “And between the throne and the four living creatures and among the elders, I saw a lamb standing, as though it had been slain, with seven horns and with seven eyes, which are the seven spirits of God sent out into all the earth.” (King James Version) The seven corners of the sign are called “horns.” But what do the “eyes” mean?
In occult schools the signs of the seven planets are written next to the seven eyes. The seven eyes signify nothing other than the seven planets, while the names of the planets designate the spirits incarnated in them as their intelligence. “Saturn” is the name of the soul of Saturn. The names of the planets come from the spirits of the seven planets found around the earth. These have an influence on human life. The lamb, Christ, contains all seven. Christ is the alpha and the omega; the seven planets are related to him like members to an entire body. The entwining of the lines of the sign portray in a wonderful way the interaction between the seven planets. From Saturn one rises to the Sun, from there down to the Moon, then on to Mars, Mercury, and so forth. The same thing is expressed in the names of the seven days of the week: Saturday, Saturn; Sunday, the Sun; Monday, the Moon; Tuesday, Mardi, Mars; Wednesday, Mercredi, Mercury; Thursday, Jeudi, Jupiter; Friday, Vendredi, Venus. Christ is the regent of all these world spheres; their actions constitute only part of his being; he unites them all. In Rosicrucian schools a lamb is often drawn as a sign for the intelligence of the Sun.
“During the first 666, dear friends, Sorat was still hidden away inside the evolutionary process of events; he was not seen in any external form, for he lived within the deeds of Arabism, and initiates were able to see him. When the second 666 years had passed he showed himself in the thinking and feeling of the tortured Templars. And before this century is out he will show himself by making his appearance in many humans as the being by whom they are possessed. Human beings will appear of whom it will be impossible to believe that they are real human beings. They will even develop externally in a peculiar manner, for outwardly they will have intense, strong dispositions with savage features and furious destructiveness in their emotions. Their faces will be like the faces of beasts. The Sorat human beings will be recognizable by their external appearance; in a terrible way they will not only scoff at everything but also oppose and want to push into the pool of filth anything that is spiritual. This will be experienced, for example, in the way something that is at present concentrated into a small space in seed form as today’s Bolshevism will become incorporated into the whole of human evolution on earth.
“That is why it is so important that all who are capable of doing so should strive for spirituality. What is inimical to spirituality will be there anyway, for it works not through freedom but under determinism. This determinism has already decreed that at the end of this century Sorat  will be on the loose again, so that the intention to sweep away anything spiritual will be deep-seated in large numbers of earthly souls, just as the apocalyptist has foreseen in the beast-like countenance and the beast-like strength that will underlie the deeds of the adversary against the spiritual. Even today the rage against spiritual things is already immense. Yet it is still only in its very early infancy.” (12 Sept. 1924, in: The Book of Revelation and the Work of the Priest, 1998, pp.117-118)
Goodness or Compassion
Goodness is the opposite of Sorat (Truth, Beauty, and Goodness):
How can man develop an actual power that will lead him directly into the world he left because he has descended to the earth from pre-earthly existence? The answer is, when he is filled with Goodness — the goodness that flows to other men and is not confined to self-interest, conscious only of what is living within his own being. Such goodness can lead the soul into the qualities, nature and experiences of others. It embraces innumerable forces of soul; and these forces are of such a nature that they actually instill into the human being elements with which he was wholly permeated only in pre-earthly existence. Through his sense of Beauty he links himself, by means of a picture, to the spirit he has left because of his descent to earthly existence. If he is truly good, he links this earthly life itself to pre-earthly existence. A good man is one who can bear his own soul over into the soul of another. Upon this all true morality depends, and without morality no true social order among earthly humanity can be maintained.
When this true morality develops into momentous impulses of will which then pass to reality in moral acts, it begins to be a quickening, all-pervading impulse in the soul, inasmuch as a man can then be moved to real sympathy at the sight of care on the face of another — his own astral body feels pain at the sight of suffering in others. For just as the sense of Truth manifests in man’s right relation to the physical body; just as a warm enthusiasm for Beauty expresses itself in the etheric body — so does Goodness live in the astral body. And the astral body cannot be healthy, or maintain its true position in the world, if man is not able to pour through it the forces proceeding from Goodness.
Truth, then, is related to the physical body, Beauty to the etheric body, Goodness to the astral body. Here we have the concrete reality of the three abstractions of Truth, Beauty, Goodness. In short, we can relate to the actual being of man all that is expressed instinctively in these three ideals.
