"The Card teaches us in the first instance that the Emperor has renounced compulsion and violence. He has no weapons. His right hand holds the sceptre forward, on which his gaze is fixed, and his left hand holds his tightly-fastened belt. He is neither standing nor sitting. ... The shield adorned with an eagle rests on the ground at his side. Lastly, he is wearing a large and heavy crown.
The context of the Card expresses active renunciation rather than the renunciation of constraint alone. The Emperor has renounced ease, being not seated. ... He may neither advance in order to take the offensive, nor move back in order to retreat. His station is by his seat and his coat-of-arms. ... He is a guardian bound to his post.
What he guards is fundamentally the sceptre. ... The Emperor has therefore renounced all action having pledged his right hand to the sceptre that he holds before him whereas his left hand holds his fastened belt. It is no longer free, because the Emperor restrains himself with it. It serves the function of holding the impulsive and instinctive nature of the Emperor in check, so that it does not intervene and divert him from his post as guardian. ...
The shield bearing an eagle rests on the ground at his side. The Emperor does not hold it with his hand, as the Empress does. The shield is certainly there, but it belongs rather to the throne than to the person of the Emperor. This means to say that the purpose for which the Emperor is on sentry-duty is not his but that of the throne. The Emperor does not have a personal mission; he has renounced this in favour of the throne. ...
God governs the world by authority, and not by force. If this were not so, there would be neither freedom nor law in the world; and the first three petitions of the Lord's Prayer (Pater Noster): 'Sanctificetur nomen tuum. Adveniat regnum tuum. Fiat voluntas tua sicut in caelo et in terra', would lose all meaning. He who prays these petitions does so solely with the purpose of affirming and increasing divine authority and not divine power. The God who is almightly—not virtually but actually—has no need at all to be petitioned that his reign may come and that his will may be done. The meaning of this prayer is that God is powerful only in so far as his authority is freely recognised and accepted. ... One is free to be believing or unbelieving. Nothing and no one can compel us to have faith—no scientific discovery, no logical argument, no physical torture can force us to believe, i.e. to freely recognise and accept the authority of God. ...
Amongst esotericists, occultists and magicians there are many—be it openly or secretly—who aspire to the ideal of the superman. In the meantime, they often pose as masters or high-priests worthy of the acclaim of the future superman. They are, at the same time, singularly in agreement in that they raise God far, very far, to the heights of Absolute Abstraction so that he does not discomfort them by his too-concrete presence, and in order that they have room for themselves to be able to develop their own greatness without the rival grandeur of the Divine to discomfort them. They build their individual towers of Babel which fall, as a rule, according to the law of all towers of Babel, and experience, sooner or later, a salutary fall, as is the teaching of the sixteenth Card of the Tarot. They do not fall from a real height into a real abyss; it is only from an imaginary height that they fall and they fall only to the ground."
