Thanks to wonderful colleagues and friends from around the world, there is a abundance of MBSR guided meditations available for free. Below, I provide links to some great resources from the University of California, San Diego (Center for Mindfulness). The links I provide below are aligned with the "assigned" meditations that follow the MBSR 8 week course.

If you are interested in deeping your knowledge of mindfulness meditation, you are welcome to read Ken Lunn's MBSR Workbook. Ken has made this resource available free of charge and is licensed under CC BY 2.0. During the MBSR course, including on the course outline, we'll share page numbers that reference to the workbook so that you are able to read later on about topics we covered in class.
