Aleister Crowley’s 21 Magickal Theorem
1. Every intentional act is a Magickal act.
Any act that is performed with intention is an act of magick. Magick, in this context, refers to the practice of using rituals, spells, and other techniques to bring about desired changes in the world. The statement implies that by focusing our intention and directing our actions towards a specific goal, we can use magick to manifest our desires and make changes in the world. This is in line with many magical traditions, which see intention as a powerful force that can be harnessed to bring about change.
2. Every successful act has conformed to the postulate.
Whatever occurs in the world happens because it was meant to happen. In other words, every event or outcome is the result of a pre-determined plan or destiny. This idea is often associated with the concept of fate, in which the course of events is determined by some external or higher power. The statement implies that there is a certain inevitability to events, and that whatever happens is meant to happen, regardless of our actions or choices. This belief may be comforting to some, as it suggests that there is a larger plan at work in the world and that everything happens for a reason.
3. Every failure proves that one or more requirements of the postulate have not been fulfilled.
Whenever a failure occurs, it is because one or more requirements of a postulate or statement of intent have not been fulfilled. In other words, the failure is a result of not following the plan or instructions that were laid out in the postulate. This implies that in order to avoid failure and achieve success, it is important to carefully follow the requirements or instructions that have been established. The statement may also suggest that by carefully examining the reasons for a failure, it is possible to identify which requirements were not met and make adjustments in order to improve the chances of success in the future.
4. Whenever a failure occurs, it is because something was not done as prescribed or instructed.
In other words, the failure can be attributed to a deviation from the established plan or procedure. The statement implies that if all elements had been carried out exactly as prescribed, the failure would not have occurred. This suggests that following instructions or rules carefully is important in order to avoid failure and achieve success.
5. The first requisite for causing any change is thorough qualitative and quantitative understanding of the conditions.
In order to cause any change, it is necessary to have a thorough understanding of the conditions surrounding the situation. This understanding should be both qualitative, meaning it relates to the qualities or characteristics of the situation, and quantitative, meaning it relates to the quantities or measurements of the situation. Without this understanding, it may be difficult or impossible to effectively cause change. In other words, the statement is emphasizing the importance of gaining a deep understanding of a situation before attempting to alter it in any way.
6. “Every man and every woman is a star”.
This phrase often associated with the religious philosophy of Thelema, which was founded by the British occultist Aleister Crowley. In the context of Thelema, the phrase suggests that every individual is a unique and powerful being, with their own inherent potential and capabilities. The phrase may be interpreted to mean that every person is like a star, shining brightly and guiding the way for others. It may also be seen as a call to individuals to recognize their own power and potential, and to strive to become the best version of themselves.
7. Every man and every woman has a course, depending partly on the self, and partly on the environment which is natural and necessary for each. Anyone who is forced from his own course, either through not understanding himself, or through external opposition, comes into conflict with the order of the Universe, and suffers accordingly.
The statement you provided suggests that every person has a natural course or path in life that is determined in part by their own individual characteristics and in part by the environment around them. This course is seen as being natural and necessary for each individual, and deviating from it can lead to conflict and suffering. The statement implies that it is important for individuals to understand themselves and their own unique qualities in order to stay on their course, and that external opposition or obstacles can also cause individuals to stray from their path. The statement may be interpreted as a reminder to stay true to oneself and to follow one’s own natural path in life, in order to avoid conflict and achieve fulfillment.
8. A Man whose conscious will is at odds with his True Will is wasting his strength. He cannot hope to influence his environment efficiently.
When a person’s conscious will, or the desires and intentions that they are aware of, is not in alignment with their True Will, they are expending their energy and resources in an ineffective manner. The True Will is a concept in Thelemic philosophy that refers to an individual’s inherent purpose or destiny, and is seen as the guiding force behind their actions and decisions. The statement implies that when a person’s conscious will is not in alignment with their True Will, they are unable to influence their environment or achieve their goals effectively. In order to be effective and efficient, the statement suggests, a person must align their conscious will with their True Will.
9. A Man who is doing his True Will has the inertia of the Universe to assist him.
When a person is acting in accordance with their True Will, they have the support and assistance of the universe behind them. The True Will is a concept in Thelemic philosophy that refers to an individual’s inherent purpose or destiny, and is seen as the guiding force behind their actions and decisions. The statement implies that when a person is acting in accordance with their True Will, they are aligned with the natural order of the universe, and as a result, they are able to draw on its power and resources to support their efforts. This may be interpreted as a reminder to stay true to one’s own purpose and path in life, in order to tap into the universal support and assistance that is available to those who are aligned with the natural order of the world.
10. Nature is a continuous phenomenon, though we may not know in all cases how things are connected.
Nature is a continuous and unbroken phenomenon, meaning that events and processes in the natural world are interconnected and ongoing. The statement implies that even though we may not always understand the specific ways in which things are connected, we can be certain that there are connections and relationships between different elements of the natural world. This may be interpreted as a reminder of the interconnectedness of all things in the natural world, and the importance of considering the potential effects of our actions on the environment and other living beings.
11. Science enables us to take advantage of the continuity of Nature by the empirical application of certain principles whose interplay involves different orders of idea connected with each other in a way beyond our present comprehension.
The statement you provided suggests that science allows us to understand and make use of the continuity of nature by applying certain principles that are based on empirical evidence, or evidence that is based on observation and experimentation. These principles are interconnected in complex ways that are not yet fully understood, but they can be used to explain and predict natural phenomena. The statement implies that by studying and understanding these principles, we can gain insight into the workings of the natural world and use this knowledge to our advantage. This may be interpreted as a recognition of the power of science to unlock the secrets of nature and allow us to better understand and interact with the world around us.
12. Man is ignorant of the nature of his own being and powers. Even his idea of his limitations is based on experience of the past, and every step in his progress extends his empire. There is therefore no reason to assign theoretical limits to what he may be, or what he may do.
Human beings are often unaware of their own capabilities and potential. It argues that our understanding of our limitations is based on our past experiences, and as we continue to grow and learn, we can extend our abilities and influence. This means that there is no reason to assume that there are certain theoretical limits to what humans can accomplish. In other words, we should not assume that there are certain things that are impossible for us to do simply because we have not done them before. Instead, we should be open to the possibility that we may be able to achieve things that we currently consider to be beyond our reach.
13. Every man is more or less aware that his individuality comprises several orders of existence, even when he maintains that his subtler principles are merely symptomatic of the changes in his gross vehicle. A similar order may be assumed to extend throughout nature.
Every individual, including human beings, is made up of multiple levels of existence or principles. These levels may be thought of as being connected to or related to one another, and may be affected by changes in the more physical or “gross” aspects of an individual. The statement also suggests that this concept of multiple levels of existence may be applicable to all of nature, not just to individual human beings. In other words, everything in the natural world may be composed of different levels or aspects that are interconnected and interdependent.
14. Man is capable of being, and using, anything which he perceives, for everything which he perceives is in a certain sense a part of his being. He may thus subjugate the whole of the Universe of which he is conscious to his individual Will.
Human beings have the ability to use or control anything that they are aware of or perceive. This is because, according to the statement, everything that a person is aware of or perceives is in some way a part of their being or existence. As a result, a person may be able to use their awareness or perception to exert their will over the entire universe of which they are conscious. In other words, the statement suggests that human beings have the potential to exert a great deal of control over their surroundings and the natural world through their ability to perceive and understand it.
15. Every force in the Universe is capable of being transformed into any other kind of force by using suitable means. There is thus an inexhaustible supply of any particular kind of force that we may need.
All forms of energy or force in the universe can be converted into other forms of energy or force through the use of appropriate methods or techniques. This means that there is an unlimited supply of any particular kind of energy or force that may be needed, because it can be obtained by converting other forms of energy or force into the desired type. In other words, the statement suggests that there is a great deal of flexibility and potential for generating different forms of energy or force in the universe, and that we can access this potential through the use of appropriate means.
16. The application of any given force affects all the orders of being which exist in the object in the object to which it is applied, whichever of of those orders is directly affected.
When a particular force is applied to an object, it has an impact on all aspects or levels of the object’s being or existence. This means that even if the force only directly affects one specific aspect or level of the object, it will still have an indirect effect on the other levels or aspects of the object’s being. In other words, the statement suggests that there are interconnectedness and interdependence between the different levels or aspects of an object’s being, and that the application of a force to one aspect of an object will have consequences for the other aspects as well.
17. A man may learn to use any force so as to serve any purpose, by taking advantage of the above theorems.
The statement you provided suggests that a person can learn to use any form of energy or force in order to achieve a specific goal or purpose. This can be done by taking advantage of the principles or theories that describe the flexibility and potential for converting different forms of energy or force into one another, as well as the interconnectedness and interdependence between the different levels or aspects of an object’s being. In other words, the statement suggests that by understanding the fundamental nature of energy and matter, a person can learn to harness and control these forces in order to achieve their desired ends.
18. He may attract to himself any force of the Universe by making himself a fit receptacle for it, and arranging conditions so that its nature compels it to flow toward him.
The statement you provided suggests that a person can draw any form of energy or force from the universe towards themselves by making themselves a suitable container or receptacle for it, and by creating conditions that will cause the force to naturally flow towards them. In other words, the statement suggests that a person can attract different forms of energy or force to themselves by being prepared to receive it and by setting up the right circumstances to draw it towards them. This may involve creating a physical space or environment that is conducive to the flow of the desired force, as well as aligning one’s own energy or state of being with the force in question.
19. Man’s sense of himself as separate from, and opposed to, the Universe is a bar to his conducting its currents. It insulates him.
The statement you provided suggests that a person’s feeling of separation and opposition from the universe can hinder their ability to channel or conduct the flow of energy or forces within the universe. This is because this feeling of separation creates a kind of insulation or barrier that prevents the person from fully connecting with and interacting with the universe. In other words, the statement suggests that a person’s sense of themselves as separate from the natural world can hinder their ability to harness and control the energies and forces within it. To be able to do so, the person must let go of this sense of separation and opposition, and instead cultivate a sense of connectedness and alignment with the universe.
20. Man can only attract and employ the forces for which he is really fitted.
The statement you provided suggests that a person can only attract and make use of the energies or forces that are suited to their own nature or abilities. In other words, a person’s potential to harness and control different forms of energy or force is limited by their own inherent qualities and abilities. For example, a person with a strong and capable physical body may be well-suited to attracting and using physical forces, while a person with a keen intellect and strong mental powers may be better suited to attracting and using more mental or psychological forces. The statement suggests that a person’s potential to use different forms of energy or force is determined by their own inherent characteristics and abilities.
21. There is no limit to the extent of the relations of any man with the Universe in essence; for as soon as man makes himself one with any idea the means of measurement cease to exist. But his power to utilize that force is limited by his mental power and capacity, and by the circumstances of his human environment.
There is no inherent limit to the extent of a person’s connection or relationship with the universe in its essence or fundamental nature. This is because, according to the statement, as soon as a person aligns themselves with a particular idea or concept, the usual means of measurement or evaluation no longer apply.
In other words, the statement suggests that a person’s connection with the universe is beyond the ordinary constraints of time and space, and is determined by their ability to align themselves with universal ideas or principles. However, the statement also suggests that a person’s ability to utilize or harness the energies and forces of the universe is limited by their mental capabilities and capacity for understanding, as well as by the conditions of their human environment. In other words, a person’s access to and control over the energies and forces of the universe is ultimately determined by their own mental and physical abilities, as well as by the conditions of their external environment.
In Conclusion
Aleister Crowley was a British occultist that believed Magick was the path to mastery by which mankind could better serve humanity. He wrote 21 Theorem in “Magick In Theory And Practice” as a mechanism to spread his teachings.
