Quick Answer
The seven Hermetic principles are a set of foundational laws describing the structure and operation of reality, codified in The Kybalion (1908) from the ancient tradition of Hermeticism attributed to Hermes Trismegistus. The seven laws are: Mentalism (all is Mind), Correspondence (as above, so below), Vibration (nothing rests), Polarity (everything has its pair of opposites), Rhythm (everything flows), Cause and Effect (every cause has its effect), and Gender (masculine and feminine principles in all things). Together they offer a comprehensive framework for understanding consciousness, reality, and the principles underlying both material and spiritual existence.

Key Takeaways
- The principles form an integrated system: Each of the seven laws is related to the others; understanding the whole provides more insight than studying any single principle in isolation.
- Mentalism is the master principle: All other principles depend on the foundational teaching that consciousness is primary, not matter.
- As above, so below has both cosmological and psychological applications: The outer world mirrors the inner world; changing the inner changes the outer.
- The Principle of Polarity offers a practical tool: Understanding that all apparent opposites are the same thing at different degrees enables the transmutation of mental and emotional states.
- These are descriptive laws, not prescriptive rules: The Hermetic principles describe how reality operates; they do not command what one should do with that knowledge.
Origin and Historical Background
The Hermetic tradition is one of the oldest and most influential streams of esoteric philosophy in the Western world. Its name derives from Hermes Trismegistus, "Thrice-Greatest Hermes," a legendary figure who represents a synthesis of the Greek deity Hermes (messenger of the gods, patron of communication and knowledge) and the Egyptian deity Thoth (the ibis-headed scribe of the gods, the keeper of cosmic records and the inventor of writing). Whether Hermes Trismegistus was a historical person, a composite of historical figures, or entirely mythological has been debated by scholars for centuries without resolution.
The foundational texts of the Hermetic tradition, collectively known as the Corpus Hermeticum, were composed primarily in Alexandria, Egypt between approximately the 1st and 4th centuries CE, in the extraordinarily fertile intellectual environment where Greek philosophy, Egyptian religion, Jewish mysticism, and nascent Christian theology were in active dialogue. The most famous single Hermetic text, the Emerald Tablet (Tabula Smaragdina), contains the key phrase "as above, so below" and was enormously influential on medieval alchemy and Renaissance natural philosophy.
The contemporary formulation of the seven Hermetic principles derives primarily from The Kybalion, a slim volume published in 1908 by three anonymous authors identifying themselves only as "The Three Initiates." The text claims to transmit the oral teaching of Hermetic masters in a form adapted for Western readers of the early 20th century. Scholars have debated its relationship to the authentic ancient Hermetic sources, with some viewing it as a significant distillation and others as a largely independent New Thought era text with Hermetic surface features. For practical spiritual purposes, The Kybalion's formulation has proven remarkably durable and useful, and its principles resonate clearly with both the ancient Hermetic texts and with parallel teachings in the Vedantic, Taoist, and Kabbalistic traditions.
Working with the Principles
The Hermetic tradition consistently emphasises that these principles are not merely beliefs to be adopted intellectually but laws to be verified through direct experience. The instruction attributed to Hermes, "Believe nothing, test everything," reflects this empirical orientation. As you study each principle, the productive question is not "Do I believe this?" but "How does this show up in my actual experience? Where do I see this operating in my inner and outer life?" Direct verification through lived experience is the Hermetic standard of understanding.
1. The Principle of Mentalism
The Kybalion states this principle as: "The All is Mind; the Universe is Mental." This is the master principle from which all others derive. It asserts that consciousness, or Mind, is the fundamental nature of reality: not an epiphenomenon of matter but the ground from which both matter and all other phenomena arise and in which they exist.
This principle challenges the materialist assumption, dominant in mainstream Western culture since the 17th century, that matter is primary and consciousness is a product of material processes in the brain. The Hermetic view is precisely the reverse: the physical world exists within and as a function of the infinite Mind that the tradition calls The All, while individual human consciousness is a point of awareness within that greater Mind. As the Corpus Hermeticum expresses it, the human mind is "the image of the Mind of the Father."
In practical terms, the Principle of Mentalism underlies all approaches to consciousness-based reality creation: the understanding that the quality of mind one brings to experience is not merely a response to external conditions but a significant shaper of those conditions. Chronic thought patterns, emotional orientations, and deep beliefs act as templates that organise experience in recognisable directions. Changing the template changes the direction of experience. This is not an invitation to magical thinking but to careful attention to the quality of consciousness one habitually inhabits.
2. The Principle of Correspondence
The Principle of Correspondence is expressed in the most famous phrase in all of Hermeticism: "As above, so below; as below, so above. As within, so without; as without, so within." This principle asserts that there is a fundamental correspondence between different planes of existence: what is true at the cosmic level is mirrored at the individual level; what operates in the spiritual realm operates analogously in the mental and physical realms; what is present in the inner world is reflected in the outer world.
The practical application of this principle is far-reaching. It means that studying the patterns of your inner life gives you genuine insight into the patterns of your circumstances. When you find yourself in recurring external situations, the Hermetic approach is to look first within for the corresponding inner pattern: the belief, fear, expectation, or emotional orientation that is resonating with and drawing those external conditions. The outer world is not random; it corresponds to the inner world. Changing the inner correspondence changes the outer pattern.
Correspondence in Astrology and Palmistry
The Principle of Correspondence is the philosophical basis for the Hermetic arts of astrology and palmistry. Astrology asserts that the positions and movements of celestial bodies correspond to patterns in individual and collective human experience: as above (the heavens), so below (human life). Palmistry asserts that the lines, mounts, and qualities of the hand correspond to the qualities and trajectory of the individual's life: as within (the constitutional and developmental history of the person), so without (the physical record of the hand). Both arts, in the Hermetic view, are expressions of a single law of correspondence that links all levels of existence.
3. The Principle of Vibration
"Nothing rests; everything moves; everything vibrates." This principle describes the fundamental dynamism of all existence. At the physical level, modern physics entirely confirms this: from the subatomic vibrations of quantum fields to the oscillations of atoms, molecules, planets, and galaxies, nothing in physical reality is actually at rest. All is motion, all is vibration, at varying frequencies and scales.
The Hermetic tradition extends this principle to non-physical domains. Thoughts vibrate at different frequencies than physical matter; emotions vibrate at different frequencies than thoughts; Spirit at the highest frequencies accessible. The practice of "raising one's vibration," common in contemporary spiritual language, derives directly from this principle: the deliberate cultivation of higher-frequency states of consciousness through meditation, gratitude, beauty, truth-telling, and service to others raises the overall frequency of one's energy field and consequently the quality of experience one attracts and creates.
Practical Applications of the Principle of Vibration
- Thought management: Recognising that chronic low-frequency thought patterns (resentment, fear, self-doubt) create a vibrational environment that attracts corresponding experiences
- Sound healing: Using specific frequencies through singing bowls, tuning forks, or voice to shift the vibrational state of the body-energy system
- Music and mantra: Specific musical intervals and mantric sounds have been used across traditions to shift consciousness through vibrational resonance
- Environmental design: Feng Shui and similar traditions operate on the principle that the vibrational quality of physical environments significantly affects the consciousness of those within them
- Crystal work: Crystals are understood in many traditions as stable vibrational structures that can entrain nearby energy fields toward their particular frequency
4. The Principle of Polarity
"Everything is dual; everything has poles; everything has its pair of opposites; like and unlike are the same; opposites are identical in nature, but different in degree; extremes meet; all truths are but half-truths; all paradoxes may be reconciled." This is perhaps the most practically useful of the seven principles for daily spiritual development.
The Principle of Polarity states that what appear to be absolute opposites are actually the same thing at different points on a continuum. Hot and cold are not different things; they are different degrees of the same quality: temperature. Love and hate are not fundamentally different emotions; they are different degrees of the same intensity of feeling directed toward the same person or object. What we call hatred is, in this view, love with its polarity reversed.
The practical implication that the Kybalion draws from this principle is the possibility of mental transmutation: the deliberate shifting of a mental or emotional state from one pole toward the other on the same continuum. Fear can be transmuted into courage; hatred into love; lethargy into enthusiasm. This transmutation is not denial or suppression but a genuine shift along the polarity of the same emotional spectrum, achieved through focused will and the application of the higher mind to the lower emotional state.
5. The Principle of Rhythm
"Everything flows, out and in; everything has its tides; all things rise and fall; the pendulum-swing manifests in everything; the measure of the swing to the right is the measure of the swing to the left; rhythm compensates." This principle describes the oscillating, cyclical nature of all processes in reality.
The Hermetic master, according to the tradition, learns to "neutralise" the rhythm: rather than being swept in both directions as the pendulum swings, they maintain a stable centre of awareness that observes the swing without being entirely controlled by it. This is not dissociation or indifference but the capacity to remain equanimous through cycles of expansion and contraction, success and setback, social engagement and withdrawal, rather than identifying with either pole.
6. The Principle of Cause and Effect
"Every cause has its effect; every effect has its cause; everything happens according to Law; Chance is but a name for Law not recognized; there are many planes of causation, but nothing escapes the Law." This principle asserts that there are no accidents in the fundamental structure of reality: every event is the effect of prior causes and simultaneously a cause of subsequent effects.
The Hermetic tradition draws an important distinction here from simple determinism. The principle does not deny freedom of will; it contextualises it. Higher causes influence lower effects. A person who operates from the level of unconscious reaction is being operated by causes they are not aware of, and their choices are therefore relatively determined. A person who operates from higher levels of conscious awareness and deliberate will initiates causes from a higher plane that override the lower-level causes. This is the Hermetic meaning of "the wise rule the stars while the foolish are ruled by them."
7. The Principle of Gender
"Gender is in everything; everything has its Masculine and Feminine Principles; Gender manifests on all planes." The Principle of Gender does not refer specifically to biological sex but to the universal presence of generative polarity: the principle that every complete act of creation requires the interaction of a projecting, initiating quality (Masculine) and a receptive, gestating quality (Feminine).
In the mental plane, the Masculine principle corresponds to focused will, directed thought, and initiating intention. The Feminine principle corresponds to receptive imagination, creative visualisation, and the gestation of ideas. Effective manifestation requires both: the directed masculine intention that plants the seed and the feminine receptive quality that allows the idea to develop, take form, and emerge rather than being forced prematurely.
Applying the Seven Laws in Daily Life
A Daily Hermetic Self-Inquiry Practice
- Mentalism check: What quality of mind am I habitually inhabiting? What thoughts, beliefs, and assumptions are creating my experience today?
- Correspondence inquiry: Where is my outer life reflecting my inner state? What external pattern is corresponding to a pattern within?
- Vibration audit: What is the overall frequency of my energy today? What is raising or lowering it?
- Polarity observation: Where am I experiencing an apparent opposite (conflict, fear, limitation)? What is the higher-frequency version of this same quality on the polarity continuum?
- Rhythm awareness: Am I in an expansion phase or a contraction phase? Am I resisting the natural direction of the current tide?
- Cause recognition: What causes am I initiating today through my choices, thoughts, and actions?
- Gender balance: Am I bringing both directed intention (Masculine) and receptive allowing (Feminine) to my current creative work and intentions?
Hermeticism and Modern Science
Several Hermetic principles appear to correspond structurally with discoveries in 20th and 21st century physics, producing an ongoing conversation between Hermetic philosophy and the philosophy of science.
| Hermetic Principle | Modern Science Correspondence |
|---|---|
| Mentalism (All is Mind) | Quantum mechanics' observer effect; the measurement problem; consciousness-based interpretations of quantum theory (Wigner, von Neumann) |
| Vibration (Everything vibrates) | Quantum field theory: matter as excitations in underlying quantum fields; string theory's vibrating strings as fundamental constituents |
| Correspondence (As above, so below) | Fractal geometry: self-similar patterns at all scales; holographic principle in theoretical physics |
| Polarity (All has its pair of opposites) | Wave-particle duality; matter-antimatter pairing; quantum superposition |
| Rhythm (Everything flows in and out) | Cyclical cosmological models; oscillating universe theories; wave functions in quantum mechanics |
These correspondences are philosophically interesting and suggestive but should not be overstated. The Hermetic principles are philosophical and experiential claims, not scientific ones, and they were not formulated with the mathematical precision that scientific theories require. What the correspondences suggest is that Hermetic thinkers, working from philosophical observation and contemplative insight across many centuries, arrived at conceptual frameworks that share important structural features with some of the most sophisticated models in modern physics.

What are the seven Hermetic principles?
The seven Hermetic principles are: Mentalism (All is Mind), Correspondence (As above, so below), Vibration (Nothing rests; everything vibrates), Polarity (Everything has its pair of opposites), Rhythm (Everything flows in and out), Cause and Effect (Every cause has its effect), and Gender (masculine and feminine principles in all things).
What is the origin of the Hermetic principles?
The Hermetic principles derive from the Hermetic tradition, a body of teachings attributed to Hermes Trismegistus, originating primarily in Alexandria, Egypt between the 1st and 4th centuries CE. The modern seven-principle formulation comes from The Kybalion, published in 1908 by three anonymous authors known as The Three Initiates.
What does As above so below mean?
As above, so below is the key phrase of the Principle of Correspondence, from the Emerald Tablet of Hermes Trismegistus. It states that the patterns operating at the cosmic scale are mirrored at every smaller scale. Understanding the laws in your inner world gives insight into the outer world, and vice versa.
How does the Principle of Vibration work?
The Principle of Vibration states that nothing rests: everything in existence is in constant motion at varying rates. Physical matter vibrates at lower frequencies; thought at higher; Spirit at the highest. This principle underlies the concept of raising one's vibration through meditation, gratitude, and alignment with truth.
What is the relationship between Hermeticism and modern science?
Several Hermetic principles correspond structurally to discoveries in modern physics. The Principle of Vibration resonates with quantum field theory. The Principle of Polarity parallels quantum superposition. The Principle of Correspondence parallels fractal geometry. These are philosophical resonances rather than scientific proofs, but they reflect the tradition's enduring conceptual sophistication.
Can the seven Hermetic principles be used for manifestation?
Yes. The Principle of Mentalism (All is Mind) provides the philosophical basis: if consciousness is primary, deliberately directing consciousness shapes experience. The Principle of Vibration underlies the law of attraction. The Principle of Cause and Effect clarifies that manifestation is the deliberate initiation of causes that produce desired effects.
Laws That Liberate
The seven Hermetic principles are not constraints but descriptions of how reality is structured, and therefore maps of how freedom within that structure is possible. Understanding that all is Mind does not make you a passive prisoner of your thoughts: it empowers you to become the conscious director of your mental life. Understanding Correspondence does not chain you to your current outer circumstances: it shows you the lever point. Understanding Polarity does not trap you in your current emotional state: it reveals that another state is already available on the same continuum, requiring only a deliberate shift of frequency.
The invitation of Hermetic philosophy is not to believe these principles but to verify them in living.
