After first hearing Sangharakshita in the late 1970's, Ratnadharini was ordained in 1989 - one of six women ordained by women preceptors – the first time in the Triratna Order outside of India. After working in a "right livelihood" business for several years, and spending some time in Melbourne, Australia, Ratnadharini was invited to move to Tiratanaloka, the newly-opened retreat centre in the UK for women training for ordination. She performed her first Private Ordinations in 2001, and her first first Public Ordinations in 2003.
After spending a few years living near Tiratanaloka, in Brecon, and working as Deputy Chair of the College of Preceptors, Ratnadharini became Chair in 2019, and returned to live at Adhisthana. She has been involved in the Adhisthana Kula, College Chair’s Council, International Council, the Restorative Project and Future Dharma Fund, and has been president to Stockholm, Helsinki, and Tiratanaloka; and in work with the Restorative project.
