Bodhicharya London is a Buddhist group under the guidance of Ringu Tulku Rinpoche, a Tibetan Kagyu lama, and is based around meditation practice and discussion. Many teachings by Ringu Tulku are available here and on YouTube.
We are non-sectarian, and the people who attend our day retreats are diverse. Some are Buddhists of different traditions, some are not. People new to meditation as well as experienced practitioners are welcome.
