According to tradition

In Yoruba tradition, Oshumaré (or Osumare) is the rainbow serpent that links heaven and earth, representing movement, cyclicality, and continuity. He governs the water cycle—rain and evaporation—and prevents the world from coming to a halt. He is an androgynous Orisha, associated with balance, vital abundance, and the flow of energies.

In the Orishas Tarot

In the deck, Oshumaré embodies the scientific healer: medicine, biology, psychology, chemistry, ecology. His arc between heaven and earth becomes a bridge between mind and body, individual and ecosystem, laboratory and forest. And here an important interpretive choice enters: the serpent’s double head, which in tradition points to cyclicality and cosmic polarity, is read here as body and psyche, two inseparable halves of the same healing process. This is not a traditional reading, but a contemporary transposition that places modern clinical understanding at the center.

Everything that lives moves in spirals: from DNA to galaxies, from umbilical cords to ocean currents, from synapses to the seasons. In that spiral, Oshumaré recognizes the signature of life and invites us to understand it, because one cannot heal what one does not understand. The rainbow imagery of the tradition—rain, water, arc—becomes biological and scientific imagery: cellular feedback, homeostasis, interdependence among species. Healing a patient and healing a river are different acts of the same intelligence. When Oshumaré appears in the deck, he speaks of health, responsibility, bioethics, and science as forms of protection for living beings.

The Light and Shadow of the archetype

Light

In his light, Oshumaré is healing, knowledge, and responsibility. He cares for body and psyche without separating them, repairs the environment, and protects the ecosystem. He is the doctor, the biologist, the therapist, the veterinarian, the physicist, the herbalist, the researcher: anyone who devotes their hands or their mind to life. Oshumaré in his light knows that there is no individual well-being without collective well-being.

Shadow

In his shadow, Oshumaré is contempt for life and for consequences. He is experiment without ethics, technology without conscience, progress without wisdom. Here we find the scientists who “want to see what happens if…,” the industries that pollute, the cynics who torture, the psychopaths who play with the body, and the ordinary people who treat the planet like a dump. The shadow destroys what the light tries to heal.

Where Oshumaré acts

He acts in hospitals, laboratories, clinics, animal shelters, universities, natural parks, pharmacies, psychotherapy practices, and in kitchens where medicinal herbs are boiling. Wherever someone tries to understand the mechanism of life or repair damage, Oshumaré passes through.

When he takes shape in a person

Whoever embodies Oshumaré wants to touch living matter: to study it, understand it, heal it. They love science but do not laugh at mystery. They look for solutions, attempt remedies, observe symptoms, read cycles. They may be a doctor, psychologist, researcher, geologist, veterinarian, herbalist, physicist, ecologist, or simply an ordinary person who defends the environment because they know that without ecosystem there is no future. Their mission is to heal, even if they are not always aware of it.

Concluding note

Oshumaré reminds us that life is a continuous and fragile circuit. Knowing where to place one’s hands is a sacred act. Science is a form of power, and every power is moral only if it bends toward care. Healing is an art; destroying is a gesture. That is why Oshumaré teaches that understanding the mechanisms of life and protecting them are both a necessity and a duty.
