What is esotericism: meaning, traditions and how to begin

Esotericism is a term that brings together different currents, practices and ways of interpreting knowledge and symbols; there is no single doctrine. In the academic study of Western esotericism the University of Amsterdam includes hermeticism, alchemy, astrology, Jewish and Christian Kabbalah and modern currents. Historical study seeks to understand how these currents formed and were interpreted; it does not assume their claims are true.

Esotericism, spirituality, religion and occultism

Esotericism refers to the study of knowledge considered inner or symbolic, often transmitted in a restricted way. Spirituality is a personal search for meaning or connection, which may or may not involve structured practices. Religion usually involves doctrines, rituals and organised communities. Occultism designates practices that explore hidden forces or knowledge, frequently associated with rituals or invocations. These categories are not absolutely opposed: a person may study esotericism as history, practise spirituality without occult rituals or participate in a religion with esoteric elements. The important thing is to distinguish historical study, personal spiritual practice and the scientific testing of a claim: a university studying a belief does not prove its efficacy.

Common symbolic methods

Tarot interprets images through decks with specific illustrations; numerology assigns themes to numbers based on calculation rules; astrology interprets celestial positions in relation to Earth. None of these methods is a scientific measurement. Crystals may be decorative or symbolic objects, but they are not medical or financial treatments. The associations are part of the tradition, not demonstrated facts about people.

How to begin: free exercise

You can start with a simple, free exercise: choose a tarot card, a symbol or a number that catches your attention. Observe the image or drawing and describe what is there, using only what you see. Then, distinguish what is personal association (what it makes you feel or remember) from a verifiable claim (something that can be confirmed by others independently of belief). Write a question that this image or symbol raises for you. Finally, look for a reliable source that deals with that symbol or method, checking who the author is, which tradition it refers to and what the limits of the interpretation are.

Choosing readings with method, source and limits

When you choose a book, article or guide, check whether it clearly identifies the method being described (for example, whether it speaks of Pythagorean, Kabbalistic or another variant of numerology), what the source of that tradition is (historical text, recognised teacher, contemporary current) and what limits the author themselves acknowledges (if they say it does not predict the future, that it does not replace professional advice or that it is merely symbolic). This helps avoid confusion between study, personal practice and claims of efficacy.

Concrete warnings

Be wary of anyone who threatens curses if you do not follow advice, guarantees specific results (such as guaranteed wealth or love), creates urgency to pay immediately or demands private data such as identity documents, bank statements or passwords. These are common practices in approaches that exploit vulnerability, not in serious study of traditions.

Differences between signs and numbers

The twelve signs of the zodiac are based on the apparent position of the Sun throughout the year, divided into twelve sectors of 30 degrees each. Each sign has an element (fire, earth, air, water) and a modality (cardinal, fixed, mutable) in astrological tradition. In numerology, numbers are derived from dates and names through specific arithmetic rules. For example, the life path reduces the day, month and year of birth separately, preserving the master numbers 11, 22 and 33 at each stage, sums those three results and reduces again, preserving 11, 22 and 33 when they appear. The name uses A=1, B=2, …, I=9, J=1 up to Z=8, summing all letters before reduction. The expression preserves 11, 22 or 33 if they appear in the total sum. The personal year uses the calendar year (January to December), reduces day, month and chosen year to a single digit each, sums and preserves 11 only if the sum is exactly 11; in other cases reduces to a single digit without preserving 22 or 33. None of these numbers reveals innate qualities, abilities, future or wealth: they are merely symbolic associations for formulating questions about one’s own experience.

Exercise with numerology

To practise, choose any date (for example, 14 March 2023). Reduce the day: 1+4=5. The month: 3. The year: 2+0+2+3=7. Sum: 5+3+7=15. Reduce again: 1+5=6. In this case, there are no masters, so the result is 6. You can use that number as a starting point for a question: “What areas of my life are asking for more balance or responsibility right now?” Then, look for a source that explains the symbolism of 6 in the tradition you are following, checking whether it speaks of responsibility, harmony or service, and whether it acknowledges that it is an association, not a prediction.

Exercise with tarot

Choose a card from a tarot deck you have to hand or can view online (such as the Fool or the High Priestess). Describe what you see: figures, objects, colours, posture. Then, think: what does this image remind me of or make me feel? That is your personal association. Now, distinguish that from a verifiable claim: “This card shows a person standing before a doorway” is observable; “This card means there will be a sudden change in my life” is an interpretation. Write a question the card raises for you: “What am I avoiding starting out of fear of the unknown?” Then, look for a guide that explains the traditional symbolism of that card, seeing whether it mentions new beginnings, innocence or risk, and whether it makes clear that it is a symbolic reading, not a prediction.

By following these steps, you are exploring a tradition in a critical and personal way, without confusing symbolism with verifiable fact. Esotericism, approached in this way, becomes a space for questions, not ready-made answers.
