Honoring Ancestors and Honoring Women–while wearing pointy hats!

Honoring those who came before us, whether familial ancestors or past-life connections with healers, seekers, seers, and wise women, we celebrated the Witches New Year together. There is certain magic made when women gather to heal, love and support each other. This holy day was transcending and divine. As we heal, the whole world heals with us, So Mote it Be!

And we met a new Goddess T’nahcne

Mabon, the season of letting go

To carry the sorrows or loss of the past year weighs heavy, and releasing the past paves way for a brighter future. At Mabon we honor the earth and the falling of leaves, reminding us that a new rebirth is just around the corner.

For this Sabbat, we gathered at Stafford Lake in Novato. Being near this body of water reminds us that Autumn sits in the West on the Wheel of the Year, and is the seat of the Matriarch, the compassionate, forgiving, and wise facet of ourselves. Blessed be this glorious time of year!

Beltane and Hieros Gamos 2022

Gathered together we shared in our circle to talk about what it means to take care of ourselves and what it is that women really want (sovereignty for me please) and then we made crowns, performed our Salt Purification Ritual, and our Hieros Gamos–or vows to ourselves, and some apprentices made their vows via iPhone because of Covid.

In the end, we received blessings from Fairy Godmother and she sang us a song, and finally, we celebrated with cherry-chocolate cake and champagne.

Ostara 2022

We gathered to celebrate Goddess Ostara, “Plant Seeds” of intention, remove “that which does not match our goals” and rejoiced in sisterhood! We had a visit from Goddess Calliope and her words of wisdom encouraged us to create by writing, drawing, gardening, or crafting into our authentic selves. (Sorry, no photo of Calliope, but maybe we will catch her on her next visit!) Blessings for a spring full of balance and hope! Blessed be!

Imbolc 2022

We began our Wheel of the Year Journey on January 29th. We are please to be surrounded by a group of lovely women who are generous, eager to learn, fabulous cooks, and inspiring sisters. As we embark on our journey we wish each apprentice the opportunity to step outside of herself, let the herself see her as the world sees her. . . a living portrait of creativity, harmony, and wisdom. Blessed Be, TD, HP xo

Established in 1998, by High Priestess Nancy Ana Dew, the Iseum of Mary Isis became a nonprofit spiritual organization honoring the Goddess.  It is our wish to bring more women into the light of their own Divine Feminine, as we become more of the change we wish to see in the world.

Nancy Dew has been on a spiritual path all of her life. In 1980, at age 38, she was going through a divorce, raising 2 wonderful daughters, working and giving much time to her daughter’s school.  As her children grew older, she realized that something was missing in her life, and she went on a deeper spiritual search that began to nourish her soul.  Studying the many aspects of alternative healing, nutrition and body work, Nancy graduated Holistic Nutritionist, Certified Clinical Hypnotherapist, Transpersonal NLP Practitioner, Massage Therapist, and Reiki Practitioner.

This path led her on an inner spiritual search and years of studying with Shamans, Cross-Cultural Anthropologists, Native Americans, Metaphysicians, Wiccans and Buddhism, living in a Buddhist Temple for a time.  What she found was that the Divine Feminine was missing in her life and her spiritual practice. She traveled the world in search of the Goddess.  Learning from the many cultures and spiritualities of South East Asia, Greece, Central and South America, Thailand, Ireland and Mexico, Nancy realized that indigenous people everywhere live immersed with the qualities of Divine Feminine Deities; a grand awakening for a woman raised in the Judeo-Christian religion!

She fell in love with the Divine Feminine and came to know Her as a part of her own soul.  She felt herself filled with the compassion, love, peace and courage of the Goddess. This led everything in her life to blossom, as if the Universe opened up a beautiful path for her to walk down.   From finding that everyone is connected to each other and to everything that is alive, she begin to lead Earth-Based Spiritual circles, or Paganism.

Nancy was Ordained a Priestess in the Fellowship of Isis in 1998, and has been leading yearlong Priestess Apprenticeships since then.  Women of all ages may enter this program, that takes place on weekends at Lilith, and honor the eight holidays on the Pagan Wheel of the Year.  Initiates learn how to create sacred space, perform rituals and ceremonies, sing, dance and drum to songs that worship the Goddess, and learn how to let go of self-limiting habits that keep women from their wholeness and authenticity.

At the end of the year, they have discovered their own inner Goddess, and are regally Ordained Priestess into The Iseum of Mary Isis, which honors each Priestess as a legal Reverend in the State of California.  Over 60 women from all walks of life have been Ordained at Lilith and share in a loving sisterhood that accepts and honors each individual’s path.
