Cowrie Shells in Yoruba and African Diaspora Traditions
Cowrie shells (Monetaria moneta and related species) are among the oldest sacred objects in documented human spiritual history, used as currency, ritual offering, and divination tool across West Africa, South Asia, East Africa, and the Caribbean for thousands of years. In the Yoruba religion and its diaspora expressions, including Santeria, Candomble, and Umbanda, cowrie shells occupy a central ritual role: they are the medium through which the Orishas communicate with practitioners during divination readings. The 18-shell set corresponds to the erindinlogun system, which uses 16 active shells plus two witness shells, creating a system of 256 possible Odu patterns, each carrying a body of oral literature and spiritual guidance.
Each shell’s two natural positions, open (natural slit facing up) or closed (rounded back facing up), function like a binary code in the hands of a trained diviner. The specific pattern of open and closed shells on a given cast corresponds to a named Odu, which the diviner then interprets according to the oral traditions associated with that pattern. The system’s depth and precision have made it one of the most sophisticated divination frameworks in any living spiritual tradition.
Cowrie Shells in Charm Bags and Altar Practice
Beyond divination, cowrie shells are used as prosperity talismans, protective charms, and altar offerings. Their historical use as currency in West African trade routes gives them a direct energetic connection to abundance and the flow of resources, making them natural additions to money-drawing charm bags, abundance altars, and workings oriented toward financial clarity or prosperity. Their feminine form, resembling an eye and a womb simultaneously, connects them to Yemaya, Oshun, and other ocean-associated or feminine Orishas in Yoruba cosmology.
In altar practice across traditions, cowrie shells are placed on Orisha-specific surfaces, used to ornament sacred objects, woven into ritual jewelry and necklaces (ileke), and incorporated into charm bags for protection and abundance. A set of 18 provides both the shells needed for erindinlogun divination practice and a supply sufficient for multiple altar and charm uses simultaneously.

How to Use Cowrie Shells in Ritual Practice
How to work with cowrie shells in divination, charm bags, and altar practice.
- Prepare Shells for Divination or Ritual Use
Cleanse the shells before first use by rinsing them in cool water, then passing them through the smoke of frankincense or copal incense. For erindinlogun divination they require formal consecration within the Santeria tradition itself.
- Perform Obi Divination with Four Shells
For basic yes or no guidance accessible to non-initiated practitioners, select four shells from the set and cleanse them specifically for this purpose. Focus your question, hold the four shells in cupped hands, and toss them onto a white cloth.
- Incorporate into Altar and Abundance Work
Place cowrie shells on altars dedicated to Oshun or Yemaya, surrounding candles and offerings. For charm bags, add three to five cowries with cinnamon, basil, or five-finger grass. Their link to currency makes them ideal for any prosperity working.
The Tarot Fellow Standard
I stock this 18-shell set because it provides the correct count for erindinlogun divination practice while also leaving shells available for the altar and charm bag uses that practitioners often combine with their divination work. The shells are natural cowries at the approximately 2.8-inch size, which is appropriate for both divination use and decorative altar placement. Santeria is a living tradition, and these shells are supplies for practice, not a substitute for initiation or for the guidance of a godparent and house.

Cowrie shells are linked to Yemaya and Oshun in Yoruba cosmology, ocean energy, feminine power, and spiritual sight. Their shape resembles both an eye and a womb, making them symbols of fertility and divine feminine energy across many traditions.
Obi divination using four shells for basic yes or no guidance is accessible to non-initiated practitioners. The deeper erindinlogun system, which uses the full 16 shells, requires initiation and training within the Santeria tradition.
Add three to five cowrie shells to a green or gold flannel charm bag alongside money-drawing herbs such as cinnamon, basil, and five-finger grass. Dress the bag with a prosperity ritual oil. The shells’ link to currency reinforces the work.
