Donna was first introduced to the Dharma in her teenage years. In 1970, having finished college, she travelled overland to India. After attending retreats in Bodhgaya with S. N. Goenka, she stayed at a Buddhist mission outside Delhi. Several people had already mentioned the name of Kalu Rinpoche to her, but it wasn’t until she met Ken McLeod at that mission that she learned
how to negotiate the logistical difficulties in getting to Darjeeling.
In 1971, she made the journey to Kalu Rinpoche’s monastery in Sonada, near Darjeeling. Her meeting with him was a turning point, solidifying her commitment to this branch of Buddhist practice. Along with other practices, Kalu Rinpoche encouraged her to study mahamudra.
Instruction and guidance was difficult to come by in those days and it was only with the 1986 publication of Tashi Namgyal’s Mahamudra: The Quintessence of Mind and Meditation, that she appreciated the full scope and range of mahamudra teaching. In the 1980’s, she attended two mahamudra retreats with Ken McLeod. She then attended four more mahamudra retreats with Thrangu Rinpoche, a senior scholar and meditation master in the Karma Kagyu tradition. In the course of these retreats, he became her principal teacher. Her transcriptions of the teachings he gave at those retreats were later published under the title Essentials of Mahamudra.
In 1990, with Thrangu Rinpoche’s blessing, she and Peter Barth, another student of Thrangu Rinpoche, co-taught a mahamudra study group for four years in Sonoma County, California. In 1996 she joined with Lama Palden, a graduate of the three-year retreat, to establish the Sukhasiddhi Foundation in Marin County, California. There she continued to teach mahamudra.
In 2006, Thrangu Rinpoche suggested she teach under his auspices in Sonoma County as part of the Vajra Vidya or Indestructible Heart Wisdom network. To this day, she continues to teach and guide students in this practice.
