In 1995, Jhenah founded the Sisterhood of Avalon, a non-profit organization with international membership that focuses on Celtic women’s mysteries and which seeks to balance intuitive wisdom with scholastic achievement. Among its activities, the SOA sponsors the Avalonian Thealogical Seminary; facilitates international training intensives; hosts spiritual pilgrimages to sacred sites in the UK and Ireland through Mythic Seeker; publishes devotional anthologies and keepsake datebooks through Ninth Wave Press; hosts an annual Celtic Women’s Spirituality event called the Ninefold Festival, and provides a variety of learning opportunities both through local hearth groups and online community support.
The Avalonian Tradition, the spiritual path taught by the Sisterhood of Avalon, takes inspiration from the enclaves of holy women found throughout the Celtic world. These enclaves existed in tandem with druidism, but seemed to serve different cultural purposes. Known to us from classical historians, folk tradition, and legends, these women’s communities have similar attributes: they are closed communities of healers, shapeshifters, oracles, weather workers, and wise women in service to Divinity. The SOA focuses on the British iteration of these enclaves, known as Ynys Afallon — the Island of Avalon.
