Ifá: patterns, poetry and ways of knowing

My spiritual and philosophical exploration of Ifá: living memory, character, poetry and patterns—and what this inheritance asks of us today.

MY PERSPECTIVE / SPIRITUALITY, KNOWLEDGE & CHARACTER

We are its continuation.

My approach to Ifá is spiritual, with a particular interest in philosophy, memory and the cultivation of character. I am drawn to how generations have thought about existence, choice, consequence and our responsibilities to one another. I respect the religious and divinatory practices through which this living tradition is sustained; my focus here is the intellectual and ethical inheritance I carry into learning, family life, AI and Tapestries.

For me, Ifá is the living memory and intelligence of Yorùbá civilization—preserving and interrogating knowledge about existence, character, consequence and the human condition across generations.

That is my personal reading, offered in conversation with a living community. Through Ọ̀rúnmìlà and the traditions associated with Ifá, I encounter reflections on ìwà, Orí, leadership, nature, prosperity and human behaviour. Philosophy, poetry, ethics and pattern-thinking meet here. “Intelligence” describes accumulated human understanding; it does not mean that Ifá is an AI model.

A familiar question, approached through another inheritance.

The computing and data-science side of me is fascinated by the 16 principal Odù and the wider arrangement of 256 signs. The mathematics is explored below; the wonder comes first. My instinctive response is: “Ẹ̀yin baba nlá baba wa… kí ló ń ṣẹlẹ̀ níbí gan-an?” Roughly: “Our great ancestors… what exactly is going on here?” Even the analyst in me has to put the spreadsheet down for a moment.

I sometimes think of Ifá as a philosophical operating system: a metaphor for organizing experience, asking questions and considering consequences. The comparison invites inquiry into knowledge and interpretation. It does not establish that modern computing descended from Ifá, equate divination with machine learning, or turn spiritual claims into experimental findings.

The question that connects my fields is enduring: how do we organize knowledge, recognize patterns, preserve experience and make better decisions under uncertainty? A pattern can help us find a story; understanding that story still depends on language, context, dialogue and judgment.

What I want our children to inherit.

For me, recovering this inheritance is also part of questioning colonial ways of seeing. Yorùbá civilization did not begin with colonial recognition. UNESCO describes the pressures colonial rule and religious discrimination placed on Ifá’s transmission. I want our children to meet their inheritance with informed confidence, while retaining the freedom to question and learn.

A child studying science or AI should be able to say: “My civilization also developed systems for thinking deeply about existence, knowledge, character and consequence.” That confidence need not depend on claiming every modern invention as an ancestral achievement. Understanding what was actually developed is already a serious education.

Knowledge asks something of its holder.

Ìwà l’ẹwà. Character is beauty. Modern AI brings me back to a longstanding ethical question: what kind of person should possess knowledge and power? Intelligence without character can be dangerous; knowledge without wisdom can harm. For people designing and using AI, that becomes a responsibility to explain decisions, acknowledge uncertainty, accept correction and consider who may bear the consequences.

We are not merely its inheritors; we are its continuation. I return to the saying “Ọgbọ́n àgbà àti ọgbọ́n ọ̀dọ́ la fi dá Ilé-Ifẹ̀”—the wisdom of the old and the wisdom of the young together built Ilé-Ifẹ̀. I take it as an invitation to receive, question, preserve and contribute something worthy for those coming after us.

Adapted from my contribution to an Ifá learning community. This is a personal reflection, not an ẹsẹ̀ Ifá or a statement on behalf of all practitioners. Historical context: UNESCO’s account of the living tradition. For a practitioner’s explanation of the 16/256 structure: Patrisse Cullors in UCLA Fowler Museum’s Vital Matters. The scholarship and differing perspectives below provide further reading.

PATTERN / MEMORY / MEANING

A knowledge tradition with many dimensions.

Ifá is an ancient Yorùbá intellectual and sacred tradition, rooted in the precolonial world. Its continuity rests on generations of practitioners transmitting verses, signs and interpretation. Surviving objects provide evidence of historical depth: The Met dates an Ọ̀wọ̀ Ifá vessel to the seventeenth–nineteenth centuries. That is a date range for an object, not the birth of Ifá. Its oral origins are older than the modern records available to us, but a precise founding year—or a claim of a fixed number of thousands of years—cannot be established from this evidence. The tradition remains living, learned and renewed.

Ifá brings a finite system of signs into conversation with an extensive, living body of oral literature. Its study opens questions about combinatorics, classification, memory, language, interpretation and ethical judgment. This page concentrates on those intellectual dimensions while recognizing the religious and community settings in which the tradition has been sustained.

UNESCO describes a corpus organized into 256 odù, with verses known as ẹsẹ̀. A sign is therefore an entry into a body of knowledge, not the whole knowledge itself. The number of verses is not fixed by the number of signs. UNESCO’s account of the living tradition.

Two marks. Eight positions. 256 patterns.

In the notation described by Morton-Williams, a sign has two columns of four positions. Each position can carry a single or double mark. Four binary choices give 16 possible columns; pairing two columns gives 256 possible signs. Sixteen have matching columns, leaving 240 with different columns. The same count can be written in two ways:

2⁴ × 2⁴ = 16 × 16 = 2⁸ = 256

This is a precise combinatorial relationship. It tells us how many arrangements are possible, without telling us how likely a physical procedure makes each arrangement or what a verse means. The 1966 studies also document variation in how principal odù are ordered and memorized. Morton-Williams, Bascom and McClelland, Two Studies of Ifa Divination, pp. 406–431.

Read more: possibility is different from probability

With independent, equally likely outcomes, every eight-position pattern has probability 1/256, about 0.391%. If the chance of a single mark is p at every position, a particular pattern containing k single marks has probability pᵏ(1−p)⁸⁻ᵏ. This calculation is for one exact pattern, not the total probability of all patterns with k single marks.

The count of 256 possibilities alone does not prove uniform probabilities. The construction of a chain, handling, contact with a surface and dependence between outcomes can matter. An empirical study would record a defined procedure, repeated observations and uncertainty before drawing conclusions. The slider exposes an assumption; it does not supply measurements of Ifá practice.

Computing offers a comparison worth exploring.

Alamu, Aworinde and Isharufe compare Ifá with computer science through binary representation, information and procedures. The strongest starting point is clear: a two-state sign system can be represented digitally. A computer can enumerate signs, store carefully attributed recordings and help learners navigate a corpus. Read their 2013 comparative paper.

Representation

Eight binary positions can be encoded as eight bits. The code describes a configuration; it does not encode every cultural association or interpretation attached to it.

Organization

A digital archive can relate an odù to multiple verses, performers, places, translations and recordings. Each item needs provenance and an account of who may access or reuse it.

Procedure

Rule-governed operations invite comparison with algorithms. Human interpretation, dialogue and embodied apprenticeship still require study in their own terms.

Evidence

Structural similarity does not demonstrate historical descent. The supplied paper does not establish that modern computer science originated in Ifá, or that a binary structure validates predictive claims.

Physics begins with what we can measure.

Sound provides a useful meeting point between cultural practice and physical inquiry. Chant and speech produce vibrations; frequency relates to perceived pitch, while timing and the changing shape of sound contribute to performance. These are measurable properties. Their cultural meanings depend on language, situation and listeners.

Adegbite describes how dùndún drums can render Yorùbá tonal patterns and familiar phrases. That opens an educational route from performance to acoustics: compare a recorded phrase, its pitch contour and a drummer’s rendering with the performer’s explanation. It does not make a drum phrase a complete substitute for speech. Adegbite (1988) · OpenStax on frequency, wavelength and sound.

Read more: questions for observation and experiment

How does a change in membrane tension affect an instrument’s sound? How do room surfaces affect reverberation and the intelligibility of a recitation? How do changes in a casting surface affect the frequency of recorded outcomes? Each question can be investigated with a stated method, measurements and reproducible analysis.

Cosmological language about forces, balance or àṣẹ belongs to philosophical and cultural interpretation. An analogy with physical “energy” is not a measured equivalence. The materials reviewed here do not establish claims that Ifá anticipated quantum mechanics or that its signs reveal physical laws. The distinction creates room for both careful scientific inquiry and serious engagement with Yorùbá thought.

A small set of signs, an expansive world of poetry.

Ẹsẹ̀ Ifá can bring narrative, praise, warning, dialogue and ethical reflection together. Sound, allusion and performance carry meaning alongside the words on a page. Translation benefits from notes explaining the speaker, setting and interpretive choices. A sign’s mathematical economy should not obscure the literary richness associated with it.

The needle and the knife: capability as a moral question.

In the preface to Ifá Dídá: An Invitation to Ifá Divination, the Solagbade Popoola Library presents a narrative in which the knife cuts cloth apart and the needle makes discarded pieces useful again. Read as literary reflection, it asks what makes power valuable: the ability to damage, or the skill to repair and create? This is a brief paraphrase of that edition’s narrative, not a new verse or a claim that every lineage tells it identically.

Read more: philosophy, interpretation and dramatic choices

Questions of responsibility, destiny, judgment and the consequences of action can be explored through these narratives. The philosophical work lies in asking how a story reasons, what it assumes and how its interpretation changes with a situation. Ọmọlúàbí provides a related vocabulary for evaluating conduct.

Olusegun Olu-Osayomi and Babatunde Adebua examine Ifá’s role in Ola Rotimi’s The Gods Are Not to Blame. Their literary analysis helps us study how prophecy, knowledge and choice shape a drama. It is evidence about interpretation and dramatic construction, not an experimental demonstration of foreknowledge. Read their study.

For Tapestries, a scene should allow audiences to hear competing obligations and judge consequences. Authenticated verses need named editions or performers; dialogue composed for the series remains clearly identified as dramatic invention. Continue into folktales and childhood learning.

Objects hold histories of people and skill.

Evelyn Roache’s study of the art of the Ifá oracle treats its carved and cast objects as a field of artistic inquiry. Margaret Thompson Drewal and Henry John Drewal’s study of a shrine in Ìjẹ̀bú is more closely situated: it follows Kolawole Ositola’s explanations of a particular family’s objects, memories and relationships.

A fine network of lines follows the face beneath an intricate crown. The title “Head, possibly a King” preserves an important uncertainty. The quiet expression and exact modelling reward slow looking: royal dignity is suggested, rather than shouted.

SIXTEEN SIGNS / MANY VOICES

The principal Odù. From sign to reflection.

What does an Odù say? A sign identifies a body of ẹsẹ̀ Ifá, not one sentence with a single fixed meaning. A particular verse, its performance and its interpretation matter. This introduction gives each of the 16 principal signs a visual form, an attributed thematic starting point and a contemporary question.

The short associations below follow Chief Awódélé Ifáyẹmí’s practitioner overview. They are not literal name translations or quotations from Odù verses. The extended reflections, fictional everyday examples and Ọmọlúàbí connections are our editorial learning suggestions, not predictions or traditional one-to-one assignments. Names, ordering and interpretation vary between lineages.

Èjì Ogbè · Using an opening well

Meaning in the linked practitioner overview: Kingship and abundance. Read the attributed account ↗

Extended reflection · our interpretation: An opportunity can enlarge responsibility as well as personal advantage. Ask who benefits from your success and whose contribution remains unseen.

Everyday example · imagined: You receive a promotion: credit the team, explain decisions and mentor the next person rather than turning access into a private privilege.

Suggested Ọmọlúàbí connection: Ìrẹ̀lẹ̀ — humility · Inú rere — goodwill.

Ask yourself: Who should share in this opportunity?

Òyèkú Méjì · Making room for change

Meaning in the linked practitioner overview: Endings and transformation. Read the attributed account ↗

Extended reflection · our interpretation: An ending need not erase what came before. Reflect on what deserves preservation and what should be allowed to end; grief does not have a deadline.

Everyday example · imagined: A family closes an elder’s old shop. They record its stories, settle obligations fairly and discuss a new use for the building together.

Suggested Ọmọlúàbí connection: Ìbọ̀wọ̀ — respect · Sùúrù — patience.

Ask yourself: What do we preserve, and what can we release?

Ìwòrì Méjì · Examining our own assumptions

Meaning in the linked practitioner overview: Inner vision and reflection. Read the attributed account ↗

Extended reflection · our interpretation: Inner conviction is worth listening to, but it is not independent evidence. Reflection becomes more useful when we can question our first interpretation.

Everyday example · imagined: An analyst suspects a supplier is causing delays. Before accusing anyone, she checks dates and discovers the approval queue is the larger problem.

Suggested Ọmọlúàbí connection: Òtítọ́ — truthfulness · Ìrẹ̀lẹ̀ — humility.

Ask yourself: What evidence might change my mind?

Òdí Méjì · Looking beneath the surface

Meaning in the linked practitioner overview: The concealed and the womb. Read the attributed account ↗

Extended reflection · our interpretation: A visible outcome can conceal the work and circumstances that produced it. Curiosity should also respect boundaries: not everything private belongs in public.

Everyday example · imagined: A pupil’s attendance falls. A teacher asks sensitively about transport and caring duties rather than announcing that the pupil lacks discipline.

Suggested Ọmọlúàbí connection: Inú rere — goodwill · Ìbọ̀wọ̀ — respect.

Ask yourself: What context is missing, and how can I ask respectfully?

Ìrosùn Méjì · Repair after disagreement

Meaning in the linked practitioner overview: Conflict and healing. Read the attributed account ↗

Extended reflection · our interpretation: Repair requires more than silence. Naming what happened, acknowledging harm and changing behaviour can matter more than winning the final argument.

Everyday example · imagined: Two relatives disagree over a shared property. They gather the records, hear each account and agree a transparent process for resolving the issue.

Suggested Ọmọlúàbí connection: Òtítọ́ — truthfulness · Ọ̀rọ̀ sísọ — responsible speech.

Ask yourself: What would repair look like to the person affected?

Ọ̀wọ́nrín Méjì · Adapting without abandoning principles

Ọ̀wọ́nrín Méjì, the matching-column sign

Meaning in the linked practitioner overview: Unpredictability and creativity. Read the attributed account ↗

Extended reflection · our interpretation: Changing circumstances call for flexible methods. A useful response can change the plan while retaining honesty, care and accountability.

Everyday example · imagined: Heavy rain disrupts a community event. Organisers explain the change, move activities indoors and arrange transport for older visitors.

Suggested Ọmọlúàbí connection: Iṣẹ́ — diligent work · Inú rere — goodwill.

Ask yourself: Which part of the plan can change while our responsibilities remain?

Obàrà Méjì · Making resources useful to others

Meaning in the linked practitioner overview: Prosperity and generosity. Read the attributed account ↗

Extended reflection · our interpretation: Having more can create room to contribute. Generosity works best with consent and transparency, rather than using a gift to control its recipient.

Everyday example · imagined: A successful trader funds apprenticeships with clear selection criteria and pays trainees fairly instead of expecting unpaid loyalty.

Suggested Ọmọlúàbí connection: Inú rere — goodwill · Ìrẹ̀lẹ̀ — humility.

Ask yourself: Does this gift increase another person’s independence?

Ọ̀kànràn Méjì · Pausing before escalation

Meaning in the linked practitioner overview: Speed and aggression. Read the attributed account ↗

Extended reflection · our interpretation: Urgency can help us act, but anger can narrow judgment. Courage can mean protecting someone immediately while refusing needless humiliation or retaliation.

Everyday example · imagined: A hurtful message appears in a group chat. A member stops its circulation, checks on the person targeted and raises the issue without reposting the insult.

Suggested Ọmọlúàbí connection: Sùúrù — patience · Ọ̀rọ̀ sísọ — responsible speech.

Ask yourself: What action protects people without increasing the harm?

Ògúndá Méjì · Power joined to responsibility

Meaning in the linked practitioner overview: Ògún and opening roads. Read the attributed account ↗

Extended reflection · our interpretation: Tools, skill and authority can remove obstacles. Their value depends on purpose, competent use and attention to the people who bear the consequences.

Everyday example · imagined: An engineer redesigns a dangerous crossing, consults residents and tests the changes instead of treating speed of construction as the only success measure.

Suggested Ọmọlúàbí connection: Iṣẹ́ — diligent work · Akínkanjú — courage.

Ask yourself: What safeguards should accompany this new capability?

Òsá Méjì · Responding to disruption

Meaning in the linked practitioner overview: Upheaval and unexpected change. Read the attributed account ↗

Extended reflection · our interpretation: A disruption can expose fragile arrangements. Reflection asks what to stabilise now and what to rebuild more fairly over time.

Everyday example · imagined: A small business loses its main customer. Its owner shares the situation honestly, reviews costs with staff and explores alternatives before making promises.

Suggested Ọmọlúàbí connection: Òtítọ́ — truthfulness · Akínkanjú — courage.

Ask yourself: What needs immediate care, and what needs a different plan?

Ìká Méjì · Allowing correction to change us

Meaning in the linked practitioner overview: Arrogance corrected through humility. Read the attributed account ↗

Extended reflection · our interpretation: Being corrected need not diminish dignity. The stronger test is whether we acknowledge the error, repair its effects and alter the practice that produced it.

Everyday example · imagined: A community leader repeats an inaccurate claim. When shown the source, he corrects it in the same public forum and thanks the person who checked.

Suggested Ọmọlúàbí connection: Ìrẹ̀lẹ̀ — humility · Òtítọ́ — truthfulness.

Ask yourself: Have I repaired the error where others encountered it?

Òtúrúpọ̀n Méjì · Perseverance with support

Òtúrúpọ̀n Méjì, the matching-column sign

Meaning in the linked practitioner overview: Suffering and endurance. Read the attributed account ↗

Extended reflection · our interpretation: Endurance should not mean accepting avoidable harm. A sustainable response may combine patient effort with asking for help and changing unreasonable conditions.

Everyday example · imagined: A student returning to mathematics struggles with calculus. She uses office hours, forms a study group and practises steadily rather than hiding the difficulty.

Suggested Ọmọlúàbí connection: Sùúrù — patience · Iṣẹ́ — diligent work.

Ask yourself: What support would make perseverance sustainable?

Òtúrá Méjì · Words that make understanding possible

Meaning in the linked practitioner overview: Diplomacy and speech. Read the attributed account ↗

Extended reflection · our interpretation: Effective speech is more than eloquence. It involves listening, stating differences accurately and making commitments people can understand and examine.

Everyday example · imagined: A mediator asks two neighbourhood groups to explain their needs, restates each view fairly and writes down the agreements before the meeting ends.

Suggested Ọmọlúàbí connection: Ọ̀rọ̀ sísọ — responsible speech · Ìbọ̀wọ̀ — respect.

Ask yourself: Could the other person recognise their position in my account?

Ìrẹtẹ̀ Méjì · Staying with worthwhile work

Meaning in the linked practitioner overview: Patience and long-term commitment. Read the attributed account ↗

Extended reflection · our interpretation: Long-term effort benefits from review. Persistence is not a reason to ignore new evidence; it can include learning, changing methods and renewing commitments.

Everyday example · imagined: A heritage group spends years documenting place names. Members record sources, invite corrections and publish manageable stages rather than claiming the record is complete.

Suggested Ọmọlúàbí connection: Sùúrù — patience · Iṣẹ́ — diligent work.

Ask yourself: What small, verifiable step can we sustain?

Ọ̀ṣẹ́ Méjì · Prosperity in relationship

Meaning in the linked practitioner overview: Wealth and Òṣun. Read the attributed account ↗

Extended reflection · our interpretation: Economic success exists within relationships. Ask how an enterprise treats the people, places and shared resources on which its prosperity depends.

Everyday example · imagined: A riverside business consults neighbours, manages waste responsibly and measures local benefits alongside revenue.

Suggested Ọmọlúàbí connection: Inú rere — goodwill · Ìbọ̀wọ̀ — respect.

Ask yourself: Who or what bears the cost of this prosperity?

Òfún Méjì · Finishing with humility

Meaning in the linked practitioner overview: Mystery and completion. Read the attributed account ↗

Extended reflection · our interpretation: Completion is a moment to account for what has been done and what remains unknown. A careful handover makes achievement useful beyond its original author.

Everyday example · imagined: A project team closes its pilot with accessible documentation, an honest account of limitations and a named owner for unresolved work.

Suggested Ọmọlúàbí connection: Ìrẹ̀lẹ̀ — humility · Iṣẹ́ — diligent work.

Ask yourself: What must the next person know to carry this forward?
