No. It is not necessary to read any books prior to attending the MBSR class. In fact during the class we recommend not reading any books, as mindfulness is a highly experiential process. We invite you to use this time to investigate your own process and experience of the course and then after it is finished it may be useful to expand your understanding by reading Full Catastrophe Living by Jon Kabat-Zinn.
