Denise Jarvie was born near Stonehenge in the south of England on November 11 and immigrated with her family to Melbourne, Australia at age three, later settling in Sydney, where she still lives. She trained as a Reiki master teacher, meditation teacher and holistic counsellor, and is a member of the International Institute for Complementary Therapists, describing fifteen years of work guiding clients through readings, meditation and Reiki before founding The Mystical Tree, a healing space in Sydney where she conducts consultations and teaches courses in tarot reading, Reiki and holistic counselling.
Her best known deck, the Flower Of Life oracle, references a geometric pattern found across multiple historical decorative traditions and used within various New Age systems as a symbol of interconnection, and was published by Blue Angel Publishing in 2015 as a fifty two card set.
She has gone on to create a series of further decks and books under related titles, including the Secret Language Of Light and Secret Language Of Darkness oracles, the Mandala Healing Oracle and the Tarot Of Light. Jarvie's claims to Reiki practice and card reading ability rest on training and certification within specific complementary therapy bodies rather than on scientific demonstration, and her decks are marketed and reviewed within the specialist tarot and oracle press, including sites such as Aeclectic Tarot, rather than through mainstream literary or art criticism.
