This is a weekly class from Deer Park Monastery on the topic "The 40 Tenets of Plum Village" and it is based on a book called Plum Village Looks at Vulture's Peak written by Thich Nhat Hanh. The book describes the essential characteristics of Plum Village practice and teachings.

In this class Brother Phap Luu discusses the 23rd tenet: "We can talk of a person as a continuous and ever-changing stream of five aggregates. This stream is always flowing. It is in connection with, receives from and contributes to other streams of phenomena. We cannot speak of a person as an unchanging and permanent separate self."
