Ruth Denison studied in Burma in the early 1960s with the meditation master Sayagi U Ba Khin. She has been teaching since 1973 and is founder of Dhamma Dena, a desert retreat center in Joshua Tree, CA, and The Center for Buddhism in the West in Germany.
Sally Clough Armstrong began practicing vipassana meditation in India in 1981. She moved to the Bay Area in 1988, and worked at Spirit Rock until 1994 in a number of roles, including executive director. She began teaching in 1996, and is one of the guiding teachers of Spirit Rock's Dedicated Practitioner Program.
Sally has always been inspired by the depth and the breadth of the Buddha’s teaching, as presented in the suttas of the Pali Canon, because the truth and power of the Buddha’s words still speak to us today. Her intention in teaching is to make these ancient texts and practices accessible and relevant to all levels of practitioner, from the very new to the dedicated meditator.
